Abstract: We theoretically study the magnetic phase diagram of a three-dimensional topological Kondo insulator by means of real-space dynamical mean field theory. We find that ferromagnetically ordered states become stable upon hole doping. Besides a wide… read more here.

DOI: 10.1103/physrevb.99.020401
Abstract: Samarium hexaboride is a topological Kondo insulator, with metallic surface states manifesting from its insulating band structure. Since the insulating bulk itself is driven by strong correlations, both the bulk and surface host compelling magnetic… read more here.

DOI: 10.1126/sciadv.aap8294
Abstract: An electrical current applied in Kondo insulator SmB6 could induce the magnetization of an adjacent ferromagnet to switch. The advent of topological insulators (TIs), a novel class of materials that harbor a metallic spin-chiral surface… read more here.
