We calculate the specific heat and susceptibility of rare-earth magnetic superconductors in the context of the Ginzburg-Landau theory. The specific heat and susceptibility are calculated both at the coexistence phase of antiferromagnetism and superconductivity and normal phase. Theoretical results are compared with experimental results, which agree excellently well.
We present an improved analysis of the phase transitions in rare earth superconductor using Ginzburg-Landau theory. Our work is based on the systematic study of critical field and superconducting order parameter in the presence of localized magnet due to rare-earth atom. We present the different phases that can occur and analyze the conditions of phase transition from the normal phase to the coexistence phase of antiferromagnetism and super-conductivity. We calculate the critical field and Ginzburg-Landau parameters to show the coexisting property. We compare our theoretical results with existing experimental results.
