摘要：

In the present study cerium substitution effects in the sol-gel derived yttrium iron garnet (Ce:Y3Fe5O12 , Ce:YIG) have been investigated. To avoid formation of CeO2 as side phase the samples were prepared under different conditions. Synthesis of Ce:YIG in the reducing atmosphere, however, showed the formation of perovskite YFeO3 as dominant phase. Mixed-metal cerium substituted yttrium aluminium iron garnets (Ce:Y3Al5-x,FexO12,Ce:YIAG) were synthesized in the form of bulk and coating. Single phase Y2.925Ce0.075Al5-xFexO12 (x = 1, 2, 3, and 4) were successfully synthesized using the same sol-gel processing route. The garnet thin films with composition of Y2.925Ce0.075Al1Fe4O12 were fabricated on a quartz substrate by dip-coating technique. The phase purity and structural features of obtained powders and thin films were evaluated using X-ray diffraction (XRD) analysis. The surface composition was determined by X-ray photoelectron spectroscopy (XPS). The morphology of synthesis products was investigated by scanning electron microscopy (SEM).
