摘要：
High-frequency magnetic thin films with cut-off frequencies well above 2 GHz and good magnetoelastic properties are key materials for the development of new magnetic devices such as remote-interrogated magnetoelastic sensors or micro-inductors. In order to achieve high cut-off frequencies the films must have high magnetization, high anisotropy field, moderate permeability and resistivity. Therefore, multilayered thin films consisting or the transition metal alloy Fe-50 Co-50 and the amorphous soft magnetic alloy Co80B20 have been developed which show cut-off frequencies higher than 2 GHz combined with good magnetoelastic properties.
