p-Wave Superconductivity in UBe13
Published Web Locationhttps://doi.org/10.1103/physrevlett.52.1915
The specific heat in the superconducting state of UBe13 shows marked deviations from BCS theory and obeys a T3 rather than an exponential law at low temperatures. A good description is obtained by the assumption of an Anderson-Brinkman-Morel p-wave superconducting state at all temperatures. The value of the spin-fluctuation parameter deduced is large and consistent with the stability of such a state. © 1984 The American Physical Society.
