Magnetic topological insulator makes its own magnetic field

Nanowerk  November 19, 2018
In experiments, a team of researchers in the US (Rice University, Oak Ridge National Laboratory, NIST) found magnons in CrI3 samples. The structure of the magnon, and the movement of the magnetic wave was quite similar to how electron waves move around graphene. Both graphene and CrI3 contain Dirac points where electrons move just like photons, with zero effective mass, and if they move along the topological edges, there will be no resistance. This is important for dissipationless spintronic applications…read more. Open Access TECHNICAL ARTICLE
