摘要：
We propose an H-T phase diagram of granular superconductors based on the separate analyses of the intragranular critical fields and of an assembly of Josephson junctions. The model is examined experimentally and its predictions are applied to several problems of high-temperature superconductivity like the H(c)2(T) enhancement with a temperature reduction, the width of the R(T) transition under an applied magnetic field, and a double-step J(c)(H) variation.
