The Josephson Ic between a Ta-wire probe and an induced, surface, singlet, superconducting state in UBe13 decreases with decreasing temperature below the bulk UBe13 Tc, in contrast to the increase seen in comparison Mo samples. This shows that the bulk UBe13 superconductivity suppresses the induced singlet superconductivity. Such suppression is evidence of a triplet super-conducting state in UBe13. Evidence is presented for phase slip between weakly coupled singlet and triplet order parameters. © 1986 The American Physical Society.

    Anomalous proximity-induced s-wave superconductivity has been observed via the ac Josephson effect and the magnetic field and temperature dependences of the Josephson current in Nb/CeCu2Si2, Nb/LaBe13, and Nb/UBe13 junctions. The origin of the proximity-induced Josephson effect and its utility in discovering the pairing type in heavy-fermion metals are discussed. © 1985 The American Physical Society.
