Description

Superconductivity with a critical temperature TC 5.25 K was recently reported in the Cr-based superconductor Pr3Cr10xN11. The large upper critical field HC2 20 T, and the strong correlation between 3d electrons derived from specific heat, suggest the unconventional superconductivity nature of this compound. We performed muon-spin rotation/relaxation (μSR) measurements on a high-quality polycrystalline of Pr3Cr10xN11 down to 0.027 K, and specific heat measurements under different magnetic fields up to 9 Tesla. Our μSR data indicate that time-reversal symmetry is broken in the superconducting state of Pr3Cr10xN11, and the superconducting energy gap is consistent with a p-wave model, which is also supported by the specific heat data.
