✦ Synopsis

Fluctuation corrections to the specific heat near Tc of a type-II superconductor in a strong magnetic field in the presence of nonmagnetic impurities are calculated by the use of the supersymmetric formalism. The case of a Poisson distribution of impurities is considered. Smearing of the phase transition is predicted for a large enough impurity concentration.
