Thermal conductivity and thermoelectric power of UBe13

Abstract

Measurements of the resistivity, thermoelectric power and thermal conductivity of the heavy fermion compound UBe13 and their relations to the temperature-upper critical field phase diagram are reported. At low temperature (T < 1 K), enormous thermoelectric powers are detected in the normal phase. The thermal conductivity obeys a T2 law in the superconducting phase with no supplementary T contribution which is not observed in the other heavy fermion compound UPt3
