High temperature magnetic topological insulators

Article in Nature, Vol. 533, Issue 7604, pp. 513, “A high temperature ferromagnetic topological insulating phase by proximity coupling”

 

Summary of article: Bi2Se3 and EuS adatom bilayer was shown to exhibit topological insulating and magnetic properties. Topological insulator is a class of relatively new materials where the properties of the material differs between the surface layer and the core. Specifically, while the surface of a topological insulator may be conducting, its core may be an insulating material. Thus, such materials afford a wide range of application potential in myriad fields; for example, the need to offer strength in the core while allowing the surface atomic layer to be conductive for enhancing electrical properties. Potential uses of these materials may lie in high performance induction coils for electric motors used in electric vehicles.
