Abstract
One inventive aspect relates to a high-frequency magnetic thin film capable of working in a GHz-level band, and an electronic device comprising the film. The film comprises a magnetic layer and an insulating layer that are laminated alternately. The magnetic layer includes a first magnetic layer and a second magnetic layer. The first magnetic layer has a higher anisotropic magnetic field than the second magnetic layer, and the second magnetic layer has a higher saturation magnetization than the first magnetic layer.
