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.
