Abstract

In this research, temperature-dependent thermodynamic magnetic field and specific heat jump of Fe-based superconductor were studied by two-band Ginzburg-Landau theory. The analytical form of the thermodynamic magnetic field was investigated by four temperature-dependent models; Chen’s model, Zhu’s model, Shanenko’s model and Changjan & Udomsamuthirun’s model. For the calculation of specific heat jump, we use the Ruthgers expression. Calculation findings indicate an inverse relationship between the critical temperature and the specific heat jump. When compared with various models, the results from Changjan and Udomsamuthirun's models suit experimental data of Ba1-xKxFe2As2 (x = 0.4) and KFe2As2 superconductors better © (2023), (Suranaree University of Technology).
