摘要：

We report muon spin rotation-relaxation measurements of the heavy fermion superconductor UPt3. The broadening of the transverse field muon precession signal sets in approximately 60 mK below T(c), a temperature which corresponds to the lower superconducting transition. In zero applied magnetic field, we observe an increase in the internal magnetic field within the superconducting state whir-h can be explained if the ''lower superconducting phase'' in the H-T phase diagram of UPt3 is characterized by broken time-reversal symmetry.
