Abstract

We reassert that the transformation from an anisotropic Ginzburg-Landau (GL) free energy to the isotropic GL free energy derived by Klemm and Clem is valid for the entire field regime, although it has been claimed that it is valid only for restricted cases. Using the transformated GL free energy, we obtain the analytic expressions of the magnetization for uniaxial superconductors. Further, combining the obtained GL free energy with Brandt’s numerical method to solve the isotropic GL equations, we numerically calculate the magnetization in the entire regime of the magnetic field.
