Effect of magnetic impurity substitution in topological Kondo insulator SmB6
ORAL
Abstract
A topological insulator is a material with topologically protected metallic boundaries and an insulating bulk. The strongly-correlated Kondo system SmB6 has recently been widely investigated owing to its promise of being the first realized topological Kondo insulator. Many results have confirmed the existence of metallic surface states and provided evidence of their non-trival topological nature. Here we report a study of the effect of magnetic transition metal impurity substitution in SmB6 on transport and thermodynamic properties, providing an important insight into the nature of the surface states.
