Abstract

In the presence of zeros of the order parameter in an anisotropic superconductor, the combined effect of a magnetic field and impurities leads to two different limiting magnetic-field dependences of the specific heat. These dependences are studied both for Born scatterers and in the unitary limit for several specific examples of anisotropic pairing. A estimate is given for the crossover field.
