Abstract
Y-Type ferrite substituted with a combination of non-magnetic lithium and aluminum, Ba2Zn2-2xLixAlxFe12O22, was synthesized by polymerized complex method and the effects of substitution on their magnetic properties were investigated. The monophasic Y-Type ferrite was obtained at the composition range up to x = 0.6 and their lattice parameters decreased isotropically by the substitution. The saturation magnetization at 10 K decreased and Curie temperature increased with increasing composition x. As a result, the saturation magnetization at room temperature showed maximum at x = 0.2 and the relative complex permeability of sintered Y-Type ferrite also showed same tendency. The substituion with a combination of non-magnetic ions could enhanced the magnetic properties of Y-Type ferrite through lattice contraction and/or site occupation of iron ions.
