Evidence for time-reversal symmetry breaking in the non-centrosymmetric superconductor LaNiC${}_2$

A. D. Hillier, J. Quintanilla, R. Cywinski

The results from muon spin relaxation experiments on the non-centrosymmetric intermetallic superconductor LaNiC${}_2$ are reported. We find that the onset of superconductivity coinci…
