contents Ferromagnetic resonance (FMR) excitation of a ferromagnetic metal single-layer film was tried by using a couple of permanent magnets as the source of the uniform static magnetic field and by using a co-planer waveguide connected with a network analyzer as the source of the radiofrequency (RF) magnetic field. A typical FMR spectrum of a ferromagnetic Ni$_{80}$Fe$_{20}$ thin film was successfully obtained and a clear electromotive force (EMF) was generated in the Ni$_{80}$Fe$_{20}$ thin film under the FMR excitation with the permanent magnets. That is, we achieved EMF generation in a Ni$_{80}$Fe$_{20}$ thin film under the FMR excitation with the permanent magnets, which can be applied as a simple energy transduction technology from ambient RF energy to electrical energy.
