CATION DISTRIBUTION IN SUBSTITUTED LITHIUM FERRITE

Magnetization data are not sufficient for a comprehensive understanding of cation distribution of substituted Li ferrites. Neutron and X-rays diffraction, and Mössbauer experiments were carried out on several Li-Zn and Li-Ti ferrites with general compositions: Fe2.5−z/2−3t/2−mLi0.5+t/2−z/2ZnzTitMnmO4 (0 < z < 0.7, 0 < t < 0.8, m is either 0 or 0.035). The agreement between Mössbauer magnetic, X-ray and neutron data give a difinitive answer about the distribution of Zn and Ti substituted lithium ferrites. © 1979 IEEE
