A schematic illustration of our sample structure and the experimental setup to detect the EMF generated in the sample under FMR

Caption

When a static magnetic field and a high frequency magnetic field are mutually-orthogonally applied to a ferromagnetic thin film (FM film), the magnetization of micro-magnets in the FM film resonantly precesses around the direction of the static magnetic field. This is the FMR phenomenon. An EMF was generated in the FM film under FMR and the EMF is detected with a voltmeter connected to the FM film. In this study, this EMF generation phenomenon is used as the resource of a new energy harvesting technology.
