Abstract

Metallic point contacts between the heavy-fermion superconductor UBe13 and the normal metal tungsten reveal superconducting anomalies due to diffusive and thermal transport as described by Maxwell's resistance. Significant Andreev reflection-derived hole currents are missing. The strongly enhanced residual contact resistances can be explained by both a badly conducting normal interface layer on the UBe13 side and ordinary reflection caused by the extremely different electronic properties on both sides of the interface.
