Abstract

It was found experimentally that the hysteresis loss in a superconducting multifilamentary wire was drastically decreased with the decrease of the filament diameter in spite of inappreciable change in the critical current density. This tendency is incompatible with the conventional theoretical prediction from the critical state model. In the present letter it is pointed out that this anomaly can be explained by taking account of a reversible motion of fluxoids in very fine filaments of df is caused by a reversible fluxoid motion.
