Abstract

Electrical resistivity, ac-susceptibility and specific heat measurements on Czochrakski-grown single-crystalline UPt₃reveal a transition into a superconducting state below 0.48 K. For the temperature dependence of the upper critical field, dB_c2/dT, a value of -4.4 T/K is found. A numerical analysis of the normal-state specific-heat data below 20 K results in a large T³ ln(T/T^*) contribution, indicating pronounced spin-fluctuation effects. The coexistence of superconductivity and spin fluctuations makes UPt₃ a unique material.
