AC Loss Characteristics of Technical High-$T_{c}$ Superconducting Tapes

The magnetization and self-field losses of the four technical high-T$_{c}$ superconducting tapes have been investigated experimentally. The results show that the magnetization losses for parallel or perpendicular fields can be well predicted from the slab model or the strip model for a filamentary region. However the magnetization losses for longitudinal fields can be rather predicted by the slab model for a decoupled filament. The self-field losses are well explained by the Norris ellipse model.l.
