Nodeless superconductivity in Lu${}_{5-x}$Rh${}_6$Sn${}_{18+x}$ with broken time reversal symmetry

A. Wang, Z. Y. Nie, F. Du +10

Evidence for broken time reversal symmetry (TRS) has been found in the superconducting states of the $R_5$Rh${}_6$Sn${}_{18}$ (R = Sc, Y, Lu) compounds with a centrosymmetric caged cry…
