Abstract

In this work, CE-YIG nanoparticles with nominal composition of Y3-xCexFe5O12 (x=0, 0.1, 0.3, 0.4, 0.5, 0.6, 0.7 and 0.8) were first fabricated by sol-gel method and then the influence of the cerium substitution on the structural and MAGNETIC PROPERTIES of garnet nanoparticles were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), fourier transform infrared (FT-IR) spectroscopy, vibrating sample magnetometer (VSM) and MOSSBAUER SPECTROSCOPY. The XRD results showed that the maximum amount of the Ce3+ substitution in YIG structure is x=0.6. Magnetic measurement shows that room temperature saturation magnetization of nanoparticles increases up to x=0.3 firstly and then decreases by increasing Ce content. The variation of saturation magnetization can be explained according to mossbauer studies. The mossbauer analysis showed that due to Ce substitution a and d sub lattice split into two pairs of distorted and undistorted sublattice. So reduction in saturation magnetization is disscused.
