摘要: The frequency dependence of magnetic ac loss thin superconductor strip subjected to an field perpendicular the surface is investigated by incorporating a flux creep model into critical state Brandt and Indenbom. It found that reduced exhibits maximum value at fm, which rapidly varying function applied field. At low field, fm becomes zero, decreases with as power law (~f − 2/n). Whereas high infinite increases frequency, still following (~f1/n). analytical results are substantiated experimental data 2D finite element simulation.
