Ez. Kuchinskii et Mv. Sadovskii, TEMPERATURE-DEPENDENCE OF THE UPPER CRITICAL-FIELD OF HIGH-T(C) SUPERCONDUCTORS - LOCALIZATION EFFECTS, JETP letters, 58(11), 1993, pp. 819-823
The anomalous temperature dependence of the orbital upper critical fie
ld H(c2) observed in epitaxial films of the Bi-Sr-Cu-O system (over a
broad temperature range) can be described satisfactorily in terms of l
ocalization effects in the 2D (or quasi-2D) case.
