摘要：

We show that the scaling procedure, recently proposed for the evaluation of the temperature variation of the normalized upper critical field of type-II superconductors, may easily be modified in order to take into account a possible temperature dependence of the Ginzburg-Landau parameter kappa. As an example we consider kappa(T) as it follows from the microscopic theory of superconductivity. (C) 2003 Published by Elsevier B.V.
