Time-reversal symmetry breaking in the noncentrosymmetric Zr${}_3$Ir superconductor

T. Shang, S. K. Ghosh, J. Z. Zhao +8

We report the discovery of Zr${}_3$Ir as a new type of unconventional noncentrosymmetric superconductor (with $T_c=2.3$ K), here investigated mostly via muon-spin rotation/relaxati…
