Özet
Temperature dependence of the critical current density j(c)(T) for the superconducting magnesium diboride MgB2 is studied in the vicinity of T-c by using a two-band Ginzburg-Landau (G-L) theory. The result is in good agreement with experimental data for a bulk MgB2. Comparision of obtained results with single-band GL theory are presented.
