A scaling theory for the diamagnetic susceptibility, χ, and the upper critical field, Hc2, of random mixtures of superconducting and insulating elements is presented. In two dimensions, the new critical exponent in this theory is related to other percolation exponents. The resulting predictions for Hc2 are compared with experiments on InGe films.On présente des lois d'échelle pour la susceptibilité diamagnétique χ, et pour le champ critique supérieur. Hc2, de mélanges aléatoires de composants supraconducteurs et isolants. En dimension deux, l'exposant critique qui apparaît dans cette théorie est relié à d'autres exposants de percolation. Les prédictions qui en résultent pour Hc2 sont confrontées à des données expérimentales sur des films In...
