✦ Synopsis

The upper critical field, the lower critical field and the critical magnetic field ratio of anisotropic magnetic superconductors are calculated by Ginzburg-Landau theory analytically. The effect of the Ginzburg-Landau parameter (j 0 ), magnetic susceptibility (v) and magnetic-to-anisotropic parameter ratio (h) on the critical field ratio are considered. We find that the value of critical field ratio increases with increasing j 0 and h, and decreases with increasing v. The highest and the lowest value of critical field ratio is found in the diamagnetic superconductors and the ferromagnetic superconductors, respectively.
