Critical temperature of magnetic superconductors by two-band Ginzburg-Landau approach

Abstract

In this research, we study the critical temperature of the two-band magnetic superconductor by Ginzburg-Landau (GL) approach in the absent of external magnetic field. There are four models of assumption used. We find the interband-to-band ratio on critical temperature formulas analytically. The critical temperature ratio decreased as the interband-to-band ratio increased.
