Summary

Sometimes, hysteresis losses in the superconducting wire are much larger than the design values. In many cases, this is a result of proximity coupling in the normal metal layers between the filaments. Determination of the lowest limit of filament spacing and diameter to which hysteresis losses decrease with decreasing filament diameter is necessary in the design of low-loss superconducting wires for alternating current use. The authors have investigated the proximity coupling in the superconductors with different filament diameters and spacings by measuring hysteresis loss and initial magnetization.
