Abstract
A correction is found to the surface tension in type-I superconductors which is proportional to the square root of the Ginsburg-Landau parameter κ. This correction is essential for obtaining the phase diagram and other thermodynamical variables of the narrow superconducting layer arising near the twinning plane in some metals.
Résumé
Une correction proportionnelle à la racine carrée du paramètre de Landau-Ginsburg κ est trouvée pour la tension de surface des supraconducteurs de type I. Cette correction est essentielle pour obtenir le diagramme de phase et les variables thermodynamiques dans l' étroite couche supraconductrice située près des plans de macle dans certains métaux.
