ELECTRICAL PROPERTIES OF Cd2+ SUBSTITUTED Li–Zn FERRITES.

Cd²⁺ substituted Li–Zn ferrite with compositional formula Li_0.4-x/2Zn_0.2Cd_xFe_2.4-x/2O₄ with x = 0.02, 0.03 and 0.04 were prepared by the conventional double sintering ceramic technique. XRD technique confirmed the formation of single phase with spinel structure. The substitution causes an increase in the lattice constant, density and DC resistivity, while the Curie temperature and dielectric constant decreases with Cd²⁺ substitution. The mechanisms involved are discussed. [ABSTRACT FROM AUTHOR]
