Abstract
Superconductivity in materials whose crystal structure lacks inversion symmetry is a prime candidate for unconventional superconductivity. A new noncentrosymmetric compound Zr3Ir crystallizes in a tetragonal α−V3S structure. The magnetization, specific heat, and muon spin rotation confirm s-wave superconductivity, having a transition temperature Tc=2.3 K. Muon spin relaxation confirms the preservation of time reversal symmetry in the superconducting ground state.
