Title: Upper critical magnetic field of the heavy-fermion superconductor UBe/sub 13/

Abstract

The temperature dependence of the upper critical magnetic field H/sub c/2(T) of the heavy-fermion superconductor UBe/sub 13/ was determined resistively. The magnitude of the initial slope of H/sub c/2(T), approx.420 kOe/K, is the largest value ever reported for a bulk superconductor. The curve of H/sub c/2 vs T has an extremely unusual shape with a linear region that persists to very low temperatures. The anomalous shape of H/sub c/2(T) cannot be accounted for by current theories of either conventional or p-wave superconductivity.
