In this study, the nanostructure of yttrium iron garnet (YIG) synthesized by the sol-gel method and the effect of annealing temperature on its structural, magnetic, and electrical properties were investigated. The dry gel was baked at different temperatures (600 to 1100 °C) and the samples were analyzed using XRD, FTIR, FESEM, VSM, and LCR tests. The results showed that at a temperature, the pure cubic garnet phase was formed and the size of the nanocrystals grew uniformly. At this temperature, the saturation magnetization was maximum and the magnetic and electrical losses were minimum, which led to the improvement of magnetic and electromagnetic properties. Also, the reduction of dielectric losses and the increase in magnetic permeability have made the sample a suitable option for application in high-frequency components such as microwave filters, magnetic sensors, and storage devices.
