اثر جانشانی آنتیموان بر ویژگی ساختاری و مغناطیسی گارنت ایتریوم آهن تهیه‌شده به روش سل ژل

In this study, antimony substituted yttrium iron garnet with a composition of  (x = 0, 0.1, 0.2) nanoparticles were fabricated by Sol-Gel method. Garnet phase formation were investigated by X-Ray diffraction (XRD) and Fourier transform infrared spectroscopy (Far FT-IR). X-ray diffraction results show that the samples in addition to garnet phase has impurity phases of YIP, α-Fe2O3  and Sb2O4 which are appeared with incease of Sb ion substitution. The garnet phase and impurity phases was calculated using the formula klug. Percentage of the Sb ion in dodecahedral sites were calculated. Finally, Magnetic properties of nanoparticles were investigated using a vibrating sample magnetometer (VSM).The VSM pattern  show that the saturation magnetization of Sb-YIG decreases as increasing the Sb concentration.
