Abstract

Magnetization is measured on several A15 V3Si single crystals. The magnetization curve of the purest sample, which is a high-κ superconductor in the pure limit, is fairly reversible, accompanied by an upward curvature near Hc2 probably caused by the Pauli paramagnetic effect. Those of the other samples show the peak effect near Hc2, and a scaling law between the pinning force density FP and the magnetic field holds. The magnetic induction B changes nonlinearly across the sample, and the sign of d2B/dr2 changes at the field where FP attains a maximum. The strain also shows the peak effect near Hc2, corresponding closely to that of the pinning force.
