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
