Anomalous s-wave proximity-induced Josephson effects in UBe13, CeCu2Si2, and LaBe13: A new probe of heavy-fermion superconductivity.

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.
