The critical current density of iron-based superconductors under magnetic field
The time-dependent Ginzburg–Landau Lawrence–Doniach model with thermal fluctuations is used to investigate the critical current density. We calculate the critical current as a function of magnetic field and temperature in the homogeneous phase. The theoretical result based on the self-consistent Gau...
