Layered room temperature pleural magnets are promising for advanced spintronics
ARPE (a) measured and calculated (b) Fermi surface of rb1-Δv2te2o. The blue and red colors in (b) indicate reverse spin polarization. This is also evidenced by the spin-resolved alpine spectra shown in (c) and (d). Credit: Zhang et al Traditionally, magnetic materials have been divided into two main categories: ferromagnets and antiferromagnets. However, over the past few years, physicists have…

Quantum breakthrough could lead to sustainable chiral spintronics
Rendering of the tilt of the relativistic Dirac cone in the bulk electronic band of a quasi-two-dimensional (2D) magnetic topological metalloid. This is achieved by hydrogen insertion, which generates a tunable low-dissipative chiral charge current. Credit: Krusin Institute A team of physicists led by Lia Krusin Erlbaum of the City University of New York has used hydrogen cations (H+) to…
