Abstract: Spinel ferrites are one of important magnetic materials which are considered to be the foundation of various technological industries. Among different spinel ferrites the Magnesium-Zinc spinel ferrite is considered important due to its remarkable magnetic and electrical properties. But in Magnesium-Zinc ferrite the presence of diamagnetic zinc and magnesium metal ions reduce the magnitude of A-B super-exchange interaction and diminishes magnetic behaviour. In the present work, the diamagnetic zinc ions have been replaced with transition metal ions (Co2+, Ni2+ and Mn2+) to enhance the magnetic behavior of magnesium-zinc ferrite. The transition metal doped magnesium-zinc ferrites synthesized using co-precipitation route have been investigated for structural, morphological, elemental and magnetic properties. The brief description of thesis which has been divided into six chapters is given below: newlineChapter 1 includes the history of ferrites and various spinel ferrite systems. The role of transition metal doping, some general applications of spinel ferrites and the motive of the present work has been given. newlineChapter 2 describes the commonly used synthesis methods for the synthesis of ferrite nanoparticles. The complete reaction mechanism utilized for the synthesis of transition metal doped magnesium-zinc ferrites have been described in detail. The characterization techniques used for the analysis of various physical properties of prepared samples are described. newlineChapter 3 describes the structural, morphological and elemental properties of transition metal doped Magnesium-Zinc ferrites. Several structural parameters have been calculated for prepared samples using the XRD data. The values of atomic % of cations and anions have also been listed. newlineChapter 4 includes the proposed cation distribution for transition metal doped Magnesium-Zinc ferrites. Various structural parameters calculated with the help of proposed cation distribution have been correlated with the obtained XRD results. newline
