Cerium-substituted yttrium iron garnet(Ce x Y 3-xFe 5O 12, Ce∶YIG) was prepared via coprecipitation. The structu re, morphology, valence state and constituent of Ce ions were investigated respe ctively. X-ray powder diffraction(XRD) analysis shows that Ce∶YIG was of singl e cubic YIG phase. The result of X-ray photoelectron spectroscopy(XPS) indicate s the Ce ions in Ce∶YIG were in the state of trivalence. Scanning electron micr oscope(SEM) demonstrates the conglobation of Ce∶YIG particles about 0.2μm scal e.The magnetic properties were studied by a vibrating sample magnetometer(VSM) a nd the result exhibits that substitution of Ce 3+ changes the magnetic para meters of YIG. The effects of doping content of Ce ions and synthesis temperatu re on valence control were discussed in detail.
