(1) Structural characterization and magnetization

of Mg 0.7Zn0.3SmxFe2_xO4 ferrites



Mg0.7Zn0.3SmxFe2_xO4 ferrites were prepared by the solid-state reaction method and were characterized by X-ray diffraction and magnetization measurements. A single spinel phase was obtained in the range 0:00pxp0:03.

The lattice parameter was found to increase at x ¼ 0:01 and then decreases up to x ¼ 0:03, which may indicate a distortion in the spinel lattice.

The saturation magnetization was found to decrease with the increase in x up to 0.04, due to the replacement of the Fe3+ ions by the Sm3+ ions.
