Direct measurement of proximity-induced magnetism at the interface between a topological insulator and a ferromagnet
When a topological insulator (TI) is in contact with a ferromagnet, both time-reversal and inversion symmetries are broken at the interface. An energy gap is formed at the TI surface, and its electrons gain a net magnetic moment through short-range exchange interactions. Magnetic TIs can host variou...
