Magnetic Properties and Applications

Magnetic properties of BiSrCaCuO and other superconducting oxide films in a technical field region were surveyed from a viewpoint of magnetic application. Permeability, hysteresis loops, magnetic anisotropy and high frequency response were measured in the superconducting region with discussion. These results seem to be well explained by the Bean model in which a number of magnetic fluxoids thread the superconductor. These films will be helpful as soft magnetic materials in a very high frequency region.
