| Abstract: | Upper critical field(HC2) of two-band superconductors was studied by two-band Ginzburg-Landau theory.The analytical formula of HC2 included anisotropy of order parameter and anisotropy of effective-mass were found.The parameters of the upper critical field in ab-plane(H||abc2) and c-axis(H||abc2) can be found by fitting to the experimental data.Finally,we can find the ratio of upper critical field in the range of experimental result. |
