Quantum anomalous Hall edge channels survive up to the Curie temperature

Quantum anomalous Hall edge channels survive up to the Curie temperature

The quantum anomalous Hall effect has so far been limited to temperature of the order of 20 mK. Here, Fijalkowski et al. report the existence of chiral edge channels up to the Curie temperature of bulk ferromagnetism of the magnetic topological insulator with a multi-terminal Corbino geometry.
