✦ Synopsis

Specific heat measurements on 2 H-TaS2 single crystals have been carried out between 0.3 and 3 K using the ac calorimetry technique. An upturn in the normal-state data, obtained below 1 K in a 50-kG applied magnetic field, was observed to depend on the measuring frequency. It may be ascribed to a nuclear contribution with a relaxation rate directly proportional to absolute temperature. The basic parameters of the superconducting state have been determined, showing that the material is a very anisotropic, three-dimensional, type H superconductor. The broad transition observed in the heat capacity measurements cannot be analyzed in terms of fluctuations, but rather results from inhomogeneity effects.

Recently, the unusual behaviour of the specific heat of the superconductors YBa2Cu307, Y2Ba4Cu7015, and YBa2Cu,~O8 at high field and low temperature was attributed to Zeeman splitting of localized states in the vortex cores [D. Sanchez et al., Physica C 200 (1992) 1]. In an attempt to detect similar
