Abstract:

The results of research of detecting the infrared laser radiation in transparent ferromagnetic yttrium iron garnet (YIG) at room temperature are presented. It is shown that the magnitude and sign of the detected signal depend essentially on the external magnetic field and the shape of magnetization curve of the ferromagnetic. The dependence of detected signal on applied magnetic field is in good agreement with static magnetization curve of the ferromagnetic sample. The detected signal is different from zero only for those values of the external magnetic field at which the magnetization curve of ferromagnetic sample is nonlinear. The detection process of an amplitude modulated electromagnetic radiation was modeled in MATLAB environment. It is shown that at the low power of laser radiation the magnitude of the detected signal linearly dependents on the laser power, which is confirmed by the experimental results.
