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…
