Temperature Dependence of the Upper Critical Field in High-Temperature Superconductors: Localization Effects
arXiv:cond-mat/9312043
Abstract
It is shown that the anomalous temperature dependence of the orbital part of the upper critical field $H_{c2}$ observed for epitaxially grown films of high-temperature superconductor $Bi-Sr-Cu-O$ (in wide temperature interval) can be satisfactorily explained by the influence of localization effects in two-dimensional (quasi-two-dimensional) case.
