摘要: The magnetic behaviors of superconducting Nb-Zr (25%) wire have been studied at 4.2°K. magnetization curve exhibits an irreversible behavior. In transverse fields the is reduced due to transport current, but in longitudinal influence current not recognized. results are explained by a phenomenological model for inhomogeneous type II superconductors. model, based on Ginzburg-Landau-Abrikosov-Gor'kov (GLAG) theory, was proposed Silcox and Rollins extended authors consider pinning effect imperfections fluxoids. calculated good agreement with experimental values. qualitatively introducing Lorentz force fluxoids into theory. dependence critical density short sample applied field also compared
