Spin polarization effects at the hinges of 3D magnetic topological insulators

Simulations of spin polarization states on the surface of three-dimensional models of magnetic topological insulators —materials largely studied in spintronics— unveil the emergence of hinge spin polarizations, with opposite sign on opposite hinges. This study, carried out at the ICN2 and published in “Physical Review Letters”, also demonstrates the possibility to generate a large resistance switch in the sample, with important implications for the design of spin-sensitive devices.
