ZrOsSi: a Z2 topological metal with a superconducting ground state
The silicide superconductors (Ta, Nb, Zr)OsSi are among the best candidate materials for investigating the interplay of topological order and superconductivity. Here, we investigate in detail the normal-state topological properties of (Ta, Nb, Zr)OsSi, focusing on ZrOsSi, by employing a combination of 29 Si nuclear magnetic resonance (NMR) measurements and …
