We report μ+zero-field relaxation and Knight shift studies of the heavy-fermion superconductors U1-xThxBe13, x=0 and 0.033. The Knight shift in UBe13shows a strong decrease as the temperature is reduced in the superconducting state, unlike U0.967Th0.033Be13in which the shift remains at about the normal state value. If the superconducting state in UBe13has odd-parity, the decrease of Kμbelow Tcsuggests that the order parameter is pinned to the lattice. Either spin-orbit scattering or the existence of two distinct superconducting states with different spin susceptibilities in the (U,Th)Be13system would explain the differences observed in the Th-doped and pure UBe13materials. The latter hypothesis would exclude conventional BCS superconductivity. No evidence for magnetic order is seen in the zero-field relaxation rate for either material down to 0.3 K. © 1986 J.C.
