    Abstract:

    We extend the Ginzburg-Landau-Abrikosov-Gor¡¯kov (GLAG) theory to account for the variation of the upper critical field with tin composition content in practical superconductor Nb3Sn. The upper critical field near the critical temperature is then extrapolated to that at temperature 0K, coinciding with the experiment results. Applying the theoretical formulas in technical Nb3Sn wires, we obtain the dependence of the composition gradient on the superconducting properties variation in the A15 layer. This explains the discrepancy induced by the inhomogeneous composition between the state-of-art scaling law results and the experiments.
