Abstract
The detection and second harmonic generation of microwave radiation in a ferromagnetic material at low magnetic bias fields was experimentally obtained at room temperature. On certain conditions, under the influence of the microwave signal, the magnetic moment of the magnetized ferrite performs nonlinear oscillations, which results the frequency conversion. The dependence of the converted signal on the magnetizing field was measured for different forms of the magnetization curve. It was shown that the conversion efficiency strongly depends on the shape of the magnetization curve of the ferromagnetic sample, as well as on the magnitude of the bias magnetic field. The results of this study may find applications for the registration and frequency conversion of radiation, for information data recording etc.
