Self-destructive effects of magnetically-doped ferromagnetic insulators
Upton NY (SPX) Jan 21, 2015
The discovery of "topologically protected" electrical conductivity on the surface of some materials whose bulk interior acts as an insulator was among the most sensational advances in the last decade of condensed matter physics--with predictions of numerous unusual electronic states and new potential applications. But many of these predicted phenomena have yet to be observed. Now, a new atomic-scale study of the surface properties of one of these ferromagnetic topological insulators reveals that t ... read more
