Effect of samarium substitution on the structural and magnetic properties of Yttrium Iron Garnet Nanoparticles prepared by Sol-gel Method
In this work, samarium ion (Sm3) substituted yttrium iron garnet nanoparticles Y3-xSmxFe5O12 (x=0.0, 0.2, 0.3) were fabricated by the sol-gel method. X-ray diffraction (XRD) patterns confirmed the pure garnet structure for all samples. The garnet phase were studied, using, Far-FTIR. The results of vibrating sample magnetometer (VSM) represents that saturation magnetization decrease with increasing samarium ion concentration. These changes assigned to the destrucive role of Sm ionic size on magnetization of substituted garnet
