我们报告了重费米子超导体PrOs4Sb12单晶样品中μ子自旋旋转的研究。在3和17 kOe下，μ子奈特位移与通过Tc到20 mK的温度无关，表明在超导状态下局部自旋磁化率不会降低。该结果证明了在PrOs4Sb12中实现了自旋三重态超导性。
We report a muon spin rotation study in single-crystalline samples of the heavy fermion superconductor PrOs4Sb12. The muon Knight shift is independent of temperature passing through T-c down to 20 mK at 3 and 17 kOe, indicating that the local spin susceptibility does not decrease in the superconducting state. This result is evidence that spin-triplet superconductivity is realized in PrOs4Sb12.
