“…Nuclear magnetic resonance measurements on floating-zone SmB 6 have been performed under hydrostatic pressures to 5 GPa [173][174][175]. The temperature dependence of the spin lattice relaxation remains activated under pressure, though the insulating gap is reduced by about 30% at 5 GPa.…”

Samarium hexaboride crystallizes in a simple cubic structure (space group #221, Pm3m), but its properties are far from being straightforward. Initially classified as a Kondo insulator born out of its intriguing intermediate valence ground state, SmB 6 has been recently predicted to be a strongly correlated topological insulator. The subsequent experimental discovery of surface states has revived the interest in SmB 6 , and our purpose here is to review the extensive and in many aspects perplexing experimental record of this material. We will discuss both surface and bulk properties of SmB 6 with an emphasis on the role of crystal growth and sample preparation. We will also highlight the remaining mysteries and open questions in the field.Rare-Earth Borides Dmytro S. Inosov (ed.
