摘要：
The anisotropy and temperature dependence of the magnetic-field penetration in superconducting UPt3 have been measured by muon spin relaxation. The extrapolated zero-temperature values for the penetration depths parallel and perpendicular to the c axis are =7070±30 and =7820±30, respectively. The temperature dependences of and are different and can both be accounted for by a superconducting gap function with a line of nodes in the basal plane and axial point nodes. © 1990 The American Physical Society.
