Topological insulators (TIs) and other non-trivial electronic states have recently attracted great attention from the condensed matter community due to their amazing  properties and potential for applications. For the TIs with 3D nature, the promising candidates are supposed to be materials which possess strong spin orbit coupling and no magnetic order. Examples of such materials are the binaries (Bi,Sb)2,(Se,Te)3, several examples of half-Heuslers compounds and the Kondo insulator SmB6. Despite the intense experimental efforts, it has been a great challenge to unambiguously establish the realization of such a state of matter in these compound materials.
In this talk, we will discuss if electron spin resonance (ESR) experiments can be used as a potential probe to detect such topologically protected metallic surface states, based on recent Intriguing ESR results from our group.
