要旨

The upper critical field H-c2(T) of a high quality single crystal of UBe13 is studied with very low noise resistivity measurements. It shows a large but finite slope of -45 T/K, an unusual temperature dependence with an inflexion point at T/T-c similar to 0.5 and a large saturated limit for T-->0 of can be H-c2(0) = 14 T. The complete temperature dependence of H-c2(T) described by a simple model of strong coupling superconductor, assuming a full Pauli limitation and the occurence of a non-uniform superconducting state (FFLO state) at low temperature.
