Magnetization dynamics of a flux control device fabricated in the write gap of a hard-disk-drive write head for high-density recording

The design concept of microwave-assisted magnetic recording (MAMR) using the flux control (FC) effect has been proposed as a technology for hard disk drives (HDDs). In this type of MAMR, the magnetization of an in-gap device (FC device) is reversed against the gap field by spin-transfer torque, enha...
