Superconductivity in materials whose crystal structure lacks inversion symmetry is a prime candidate for unconventional superconductivity. A new noncentrosymmetric compound ${\mathrm{Zr}}_{3}\mathrm{Ir}$ crystallizes in a tetragonal $\ensuremath{\alpha}\ensuremath{-}{\mathrm{V}}_{3}\mathrm{S}$ 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 …
