Investigations of the superconducting ground state of Zr${}_3$Ir: Introducing a new noncentrosymmetric superconductor

Abstract

Superconductivity in materials whose crystal structure lacks inversion symmetry is a prime candidate for unconventional superconductivity. A new noncentrosymmetric compound Zr${}_3$Ir crystallizes in a tetragonal $\alpha$-V${}_3$S structure. The magnetization, specific heat and muon spin rotation confirm s-wave superconductivity, having a transition temperature T${}_c$ = 2.3 K. Muon spin relaxation confirms the preservation of time reversal symmetry in the superconducting ground state.
