A cobalt-free compositional strategy was pursued to promote Ce incorporation in M-type SrFe12O19 and thereby enhance its hard magnetic performance. In Sr1−xCexFe12−xMgxO19 (x = 0–0.15), the highest coercivity and finest microstructure were obtained at x = 0.1; however, a residual CeO2 phase persisted at all substitution levels, suggesting…
A research team led by Prof. YIN Lihua from the Institute of Solid State Physics, Hefei Institutes of Physical Science, Chinese Academy of Sciences, and their collaborators have found that TlGaS₂, a two-dimensional material, shows both in-plane and out-of-plane polarization. The…
Researchers have made an extremely thin material retain electrical and magnetic properties that usually disappear when it is reduced to chip-sized layers. The advance could help bring lower-energy memory and computing components closer to practical use. The material, bismuth ferrite,…
The nature of stacking faults (SF) â whether intrinsic or extrinsic â plays a pivotal role in defect-mediated processes in crystalline materials. Yet, transmission electron microscopy (TEM) techniques for their reliable analysis remain limited to... Uncover the latest and most…
Rachel Nickel, postdoctoral scientist with ESRF, contributed to the experimental design and execution on the ID32 beamline, helping to validate the altermagnetic characteristics of manganese telluride. The rapid confirmation of altermagnetism, as noted by researchers, is particularly noteworthy. By 2024, there were…
Jun 12, 2019, 06:14 ET A 2D device of ReS2 was fabricated. After examining its configuration using atomic force microscopy (AFM), anisotropic properties were investigated by both optical and electrical methods. In addition, when the same experiment using a single device was repeated 28 times, almost…
Researchers have built a vertical organic spin–field device that lets electric fields directly control spin-polarized currents at room temperature, an advance they report in Nature Electronics. The work addresses a long-standing requirement for practical spin-based logic: electrical control over…
lead image Han et al. developed an optical microscopy probe capable of operating in magnetic fields as strong as 42 Tesla and at temperatures as low as 1.8 K. “Water-cooled magnets have a large overall footprint but a very small bore,” said author…
Researchers patterned anisotropic rhenium disulfide into resonant metasurfaces whose quasi-bound states in the continuum split into half-integer polarization singularities, producing directional photonic and polaritonic flatbands with strongly suppressed group velocity.
Researchers combined a fabricated grating with an ultrafast optically induced lattice in a low-index transparent conducting film, producing a reconfigurable spatio-temporal photonic metalattice whose diffraction rivals that of a physical nanostructure.
Magnetic materials, topological materials, altermagnets, multiferroics and spintronics, and the materials behind quantum devices.
