Abstract

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.
