Infrared Spectra and Magnetic Studies of Trivalent Doped Li-Ferrites

Abstract

Samples of Li0.5Fe2.5–xRxO4 (R = Al, Gd, Sm and La; x=0 and 0.1) were prepared by the standard ceramic method. The effect of trivalent ion substitution on the structure and on the magnetic properties of Li-ferrite has been studied. It is found that the Gd ion substitution improves the different magnetic properties of Li-ferrite while the La ion substitution has no effect on these properties.
