Abstract
Temperature dependence of the upper critical field H-c2(film)(T) of thin films of two-band superconductors is studied using the two-band Ginzburg-Landau (G-L) theory. The results are shown to be in qualitative agreement with experimental data for the superconducting magnesium diboride MgB2 films.
