Description

Electrical resistivity, ac-susceptibility and specific heat measurements on Czochralski-grown single-crystalline UPt3 reveal a transition into a superconducting state below 0.48 K. For the temperature dependence of the upper critical field, dBsub(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/Tsup(*)) contribution, indicating pronounced spin-fluctuation effects. The coexistence of superconductivity and spin fluctuations makes UPt3 as unique material. (orig.)
