The detection of amplitude-modulated microwave radiation (1.07-2.14 GHz) in the ferromagnetic yttrium iron garnet (YIG) at room temperature was experimentally obtained. The detected signal (the change of magnetic moment of YIG sample under the influence of microwave magnetic field) was recorded by the magnetic sensor representing a horseshoe-shaped ferrite with an inductor. It is shown that the magnitude and sign of the detected signal depend essentially on the slope of the magnetization curve (on the differential magnetic permeability) and on the bias magneticfield (on the bias current of the magnetizing coil). The dependence of the magnetic permeability andthe detected signal on the bias current shows that they have hysteretic behavior. The dependence ofdetected signal on applied magnetic field (bias current) is in good agreement with static curve of differential magnetic permeability of the ferromagnetic sample.
