Abstract
The upper and lower critical fields, and the critical field ratio of an anisotropic two-band magnetic superconductor in the GinzburgLandau (GL) scenario is derived analytically. The temperature-dependent upper critical field is investigated and applied to Fe-based superconductors. We find that a very high value of zero-temperature upper critical field in Fe-based superconductors can be found in the negative differential susceptibility region. The temperature-dependent upper critical field is presented in two formulas, in the empirical view and in the GL two-band view, which agrees with the experimental results. © 2011 Elsevier Ltd.
