Abstract

The fluctuation specific heat above transition for a clean superconductor in a uniform magnetic field is calculated microscopically for fixed temperature and varying field. It does not exhibit the premature breakdown of the Ginzburg-Landau approximation, arising from failure of the (∇/i)2→(∇/i+2eA/;ℏc)2 substitution that was found previously for the clean fluctuation diamagnetism.
