  A systematic treatment of the magnetic fluctuations effect on the properties
of the normal-to-superconducting phase transition in a zero external magnetic
field is given within the self-consistent approximation and the
quasi-macroscopic Ginzburg-Landau model. New results for thin superconducting
films are presented. Thermodynamic quantities having a direct experimental
interest as the order parameter jump, latent heat, and specific heat are
considered and numerically evaluated for bulk Al and thin Al films. The
possibility for an experimental verification of the theoretical predictions is
discussed.
