摘要

Magnetic properties of a thin cold-rolled Nb-Ti superconducting tape with high anisotropy of current-carrying capacity were studied experimentally and then numerically simulated. It was shown that a fish-tail effect appears in inclined magnetic fields on the steady branch of magnetization loop, while there are no features appear on the virgin branch of magnetization curve. The fish-tail effect was the more intense the more the direction of the field deviated from the normal direction. The simulation showed that the strong anisotropy of current carrying capacity is the cause of the fish-tail effect. The consequence of this for determination of the critical current density by the width of the hysteresis loop is discussed.
