Evidence for Weak Spin–Orbit Interaction Experienced by Cooper Pairs in the Spin-Triplet Superconductor UPt3: 195Pt-NMR Study

195Pt-NMR measurements for H ∥ c in the vicinity of the upper critical field \(H_{\text{c2}}^{\| c}\) have been carried out on the heavy-fermion superconductor UPt3. The 195Pt NMR line does not cha...
