This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. The researchers, Joel K. W. Yang, et al., from the Institute of Materials Research and Engineering and the Data Storage Institute at A*STAR (the Agency for Science, Technology and Research) in Singapore, as well as the National University of Singapore, have published their study in a recent issue of Nanotechnology. As Yang explained, the new method pushes the boundaries of hard disk drive recording densities.“Yes, 3.3 Tbit/in2 is one of the highest demonstrations to date,” Yang told PhysOrg.com. “Though there are other non-magnetic patterns that have higher densities, we believe we’ve fabricated and tested magnetic bits that are the most densely packed.”Today’s hard disk drives have recording densities of up to 0.5 Tbit/in2, but improving this density beyond 1-1.5 Tbit/in2 may not be possible using the same granular method. The difficulty stems from two limits. The first is a limit on the minimum number of grains per bit (each bit requires at least a few tens of grains), which is due to the need for a sufficient signal-to-noise ratio. The second limit is the superparamagnetic limit, which limits the minimum grain size. If the grain size is too small, the magnetization state becomes thermally unstable and the grains can no longer store data.In contrast with the conventional method, patterned media (or bit-patterned media) doesn’t face the same limits. Because the magnetic cells are lithographically patterned in ordered arrays, the signal-to-noise ratio is significantly improved, and each individual magnetic cell can serve as a bit. And since the magnetic cells are larger than the grains, they don’t run into the superparamagnetic limit. By overcoming the limitations of granular media, patterned media has the potential for achieving recording densities well beyond 1 Tbit/in2. Some patterned media techniques have even demonstrated original pattern resolutions of up to 10 Tdot/in2 (before the dots become functional bits), but these fabrication techniques rely on pattern-transfer methods such as etching or liftoff that degrade the resolution of the original pattern, and reduce the final density. (a, b) In the first step of the process, tiny pillars are patterned onto a surface. (c, d) In the second step, a magnetic film is deposited onto the posts, turning them into magnetic bits. The 35-nm spacing corresponds to a recording density of 0.6 Tbit/in2. A sample with 15-nm spacing (not shown) corresponds to a recording density of 3.3 Tbit/in2.

DOI:10.1088/0957-4484/22/38/385301 ‘3-D towers’ of information double data storage areal densitycenter_img (PhysOrg.com) — In an effort to increase the recording densities of hard disk drives, patterned media has become one of the most promising strategies for achieving recording densities beyond 1 Tbit/in2. In patterned media, data is stored in a uniform array of magnetic cells that each contain one bit, rather than in groups of randomly arranged magnetic nanograins in a thin-film magnetic alloy, as in today’s hard disk drives. In a new study, researchers have developed a simplified patterned media method by reducing the number of steps in the process, and have demonstrated high densities from 1.9 Tbit/in2 to 3.3 Tbit/in2, although the latter density still needs to be characterized by higher resolution magnetic force microscopes than were available for the study.

Their technique consists of just two steps: (1) using electron beam lithography to pattern arrays of dots (or tiny pillars) as small as 10 nm in diameter on a resist material, and (2) using sputtering techniques to deposit 21-nm-thick magnetic films on top of the entire resist material. The magnetic material that lands on top of the nanoposts serves as magnetically isolated bits. By avoiding etching and liftoff processes, the resolution of the final patterns are basically identical to the resolution of the original lithographic pattern.“The etching step could be avoided as the e-beam pattern resist itself, while being an excellent imaging medium for the electron beam, doubles up as a robust material that can be used in hard-disk platters,” Yang explained.Using the new method, the researchers fabricated samples with a patterning density of up to 3.3 Tdot/in2, and scanning-electron microscope images showed that the final magnetic bits maintain the same densities, up to 3.3 Tbit/in2. Because the magnetic bits are physically connected to their neighbors by tiny magnetic links, the researchers had to confirm that the individual bits were still magnetically isolated and that these links did not interfere with each bit’s ability to store data. To do this, they observed the samples under a magnetic force microscope while applying magnetic fields of different strengths to switch individual bits. For samples with densities up to 1.9 Tbit/in2, the microscope showed that individual bits can be switched independently of their neighbors; beyond that, the microscope could not resolve individual bits due to its own resolution limit.“The biggest advantage of this technique is that the final density/resolution of the fabricated bits were kept as close as possible to that of the lithographic step,” Yang said. “If we had introduced pattern-transfer steps such as etching, the maximum achievable resolution would be significantly lower due to pattern degradation during etching. As a bonus, reducing steps also reduces cost and increases throughput, especially when combined with high-throughput processes such as nanoimprint lithography and guided self-assembly.”The researchers predict that higher resolution magnetic force microscope techniques will verify the individual switchability of the bits at 3.3 Tbit/in2. They also predict that the new patterned media technique can enable the fabrication of memories at the highest possible densities (in the range of 10 Tbit/in2). If the electron beam lithography step can be combined with, or replaced by, other scalable patterning methods such as templated self-assembly, the new technique could be used for the large-scale manufacturing of future ultrahigh-density hard disk drives.last_img read more

Impostor planet exposed by astronomers Journal information: Monthly Notices of the Royal Astronomical Society (Phys.org)—Using the gravitational microlensing method, an international team of astronomers has recently detected a new gas giant exoplanet three times more massive than Jupiter. The newly discovered planet received designation OGLE-2014-BLG-0676Lb and is an important addition to the short list of extrasolar worlds detected by the microlensing technique. The discovery was described in a paper published Dec. 12 on arXiv.org.

Rattenbury et al. Faint source star planetary microlensing: the discovery of the cold gas giant planet OGLE-2014-BLG-0676Lb, Monthly Notices of the Royal Astronomical Society (2016). DOI: 10.1093/mnras/stw3185 , On Arxiv: https://arxiv.org/abs/1612.03511AbstractWe report the discovery of a planet —- OGLE-2014-BLG-0676Lb —- via gravitational microlensing. Observations for the lensing event were made by the MOA, OGLE, Wise, RoboNET/LCOGT, MiNDSTEp and μFUN groups. All analyses of the light curve data favour a lens system comprising a planetary mass orbiting a host star. The most favoured binary lens model has a mass ratio between the two lens masses of (4.78±0.13)×10−3. Subject to some important assumptions, a Bayesian probability density analysis suggests the lens system comprises a 3.09+1.02−1.12 M_jup planet orbiting a 0.62+0.20−0.22 M_sun host star at a deprojected orbital separation of 4.40+2.16−1.46 AU. The distance to the lens system is 2.22+0.96−0.83 kpc. Planet OGLE-2014-BLG-0676Lb provides additional data to the growing number of cool planets discovered using gravitational microlensing against which planetary formation theories may be tested. Most of the light in the baseline of this event is expected to come from the lens and thus high-resolution imaging observations could confirm our planetary model interpretation. Unlike other methods of detecting exoplanets, microlensing is most sensitive when it comes to searching for exoworlds that orbit around one to 10 AU away from their host stars. These planets are of special interest for astronomers studying planetary formation theories due to proximity to their parent stars, within the so-called “snow line.” Just beyond this line, the most active planet formation occurs; therefore, understanding the distribution of exoplanets in this region could offer important clues to how planets form.So far, 47 planets have been discovered by microlensing. Currently, several ground-based observation programs routinely monitor dense stellar fields to search for microlensing events. When a new event is discovered, an alert to the broader scientific community is issued in order to allow follow-up observations. Astronomers are particularly interested in events showing evidence for perturbations that could be due to the presence of a planet, or which are predicted to have a high sensitivity to such perturbations.OGLE-2014-BLG-0676, discovered in April 2014 by a Polish astronomical project called the Optical Gravitational Lensing Experiment (OGLE), is one of those interesting microlensing events. Recently, a collaboration of researchers consisting of the OGLE group, the Microlensing Observations in Astrophysics (MOA), the Wise Observatory Group and the Microlensing Network for the Detection of Small Terrestrial Exoplanets (MiNDSTEp), has detected an anomalous signal in this event consistent with a planetary lens system.”The source star passed through the central caustic, with the second caustic crossing being well recorded by the MOA microlensing survey collaboration. Observations at epochs between the unrecorded first caustic crossing and the second caustic crossing were made by the OGLE, Wise and MOA collaborations. (…) All analyses of the light curve data favor a lens system comprising a planetary mass orbiting a host star,” the paper reads.According to the research, the newly discovered planet has a mass of about 3.1 Jupiter masses and orbits its parent star at a deprojected orbital separation of about 4.4 AU. The host star is approximately 38 percent less massive than our sun and was classified as a K-dwarf. The distance to the lens system is about 7,200 light years.Moreover, the team revealed some information about the source star. They revealed that is rather faint and very red, noting that there is a possibility that the source may be blended with a nearby red star, causing an incorrect identification of the source star type.In conclusion, the scientists emphasize the importance of their discovery, noting that OGLE-2014-BLG-0676Lb could serve as a test bed for planet formation scenarios. “Planet OGLE-2014-BLG-0676Lb can be added to the growing list of planets discovered by microlensing against which planetary formation theories can be tested,” the researchers wrote in the paper.last_img read more
