ENHANCEMENT OF SURFACE BARRIER DIAMAGNETISM, PARAMAGNETISM, AND CRITICAL CURRENT IN NB3ZR WIRES IN TRANSVERSE FIELDS BY AXIAL MAGNETIC FIELDS.

Abstract

The surface 'barrier,' the diamagnetic magnetization, the residual flux, and the critical current of Nb3Zr wires in transverse fields can all be enhanced by a factor of approx. = 3 by axial magnetic fields. It is argued that this arises because the pinning force density at the surface and in the bulk increases as B to the nth power where 0.5 n 1.0. The role of azimuthal currents and the effects on alternating-current losses are discussed. (Author)
