摘要: The magnetization loops of powdered Nb/sub 3/Sn, 3/Al, V/sub 3/ Ga, and 3/Si do not close symmetrically about the applied magnetic field axis with decreasing particle size, as should be expected if high-field superconductivity originates solely from presence physically real superconducting filaments. asymmetric obtained have a form very similar to that predicted by negative surface energy models superconductivity. results for four intermetallics in terms induced current density at which fluxoids first penetrate into superconductor are presented discussed.
