SOFT MAGNETIC EXCHANGE-COUPLED COMPOSITE STRUCTURE, AND HIGH-FREQUENCY DEVICE COMPONENT, ANTENNA MODULE, AND MAGNETORESISTIVE DEVICE INCLUDING THE SOFT MAGNETIC EXCHANGE-COUPLED COMPOSITE STRUCTURE

摘要

A soft magnetic exchange-coupled composite structure, and a high-frequency device component, an antenna module, and a magnetoresistive device including the soft magnetic exchange-coupled composite structure, include a ferrite crystal grain as a main phase and a soft magnetic metal thin film bound to the ferrite crystal grain by interfacial bonding on an atomic scale. A region of the soft magnetic metal thin film adjacent to an interface with the ferrite crystal grain includes a crystalline soft magnetic metal.
