The temperature dependent surface critical magnetic field (H c3 ) of K 0.73 Fe 1.68 Se 2 superconductor by semi-anisotropic two band Ginzburg-Landau approach

Abstract In this study, we used a two-band Ginzburg-Landau technique to investigate the surface critical magnetic field ( H c3 ) of magnetic superconductors, with the first band being an anisotropic superconductor and the second band being an isotropic superconductor. Following the calculation of th...

Summary:Abstract In this study, we used a two-band Ginzburg-Landau technique to investigate the surface critical magnetic field ( H c3 ) of magnetic superconductors, with the first band being an anisotropic superconductor and the second band being an isotropic superconductor. Following the calculation of the 1 st Ginzburg-Landau equation, a surface critical magnetic field and its temperature dependent surface critical magnetic field were solved analytically using the variation method. Based on Changjan and Udomsamuthirun’s temperature dependency model, we discovered that fits best with experimental data of K 0.73 Fe 1.68 Se 2 superconductor, vicinity of the critical temperature.
