INTERACTION OF CONDUCTION AND INDUCED CURRENTS IN Nb3Zr WIRES SUBJECTED TO AXIAL FIELDS

Abstract
A residual magnetization induced in Nb3Zr wires by axial fields appreciably enhances Ic . Further, the presence of a conduction current as an axial field Hz is removed not only leads to considerably increased residual moments but also enables the wire to support currents at H = 0 much larger than is possible in the virgin state.
