Sketch of planar Hall effect (PHE) in topological Weyl semimetals with magnetic and electric fields aligned in the same direction. In this case, the trace of the PHE conductivity Tr[X] is in direct ...
Heterostructures consisting of magnetic insulator layers (e.g., EuS, YIG) and topological insulator films have also been explored for realizing QAH insulators. The proximity-induced magnetic exchange ...
