Structural and Magnetic Properties of Zn-Ni Ferrite Synthesized by Precursor Method

Vikas J. Pissurlekar

Abstract: In this work nickel zinc ferrite with general formula ZnxNi (1-x) Fe2O4 (x = 0.3, 0.4, 0.5 0.6 and 0.7) were synthesized by precursor decomposition method starting from metal nitrates. X-ray analysis indicated the formation of well crystallized Zn Ni ferrite. The change in the particle size with increasing Zn content was confirmed by scanning electron microscopy which revealed that the powders prepared by precursor method resulted in nano sized particles with a particle size of 1942 nm. The crystallite size and lattice parameter increased and Curie temperature decreased as the concentration of Zn increased. Saturation magnetization and remnant magnetization, both, continuously increase up to x=0.5, and then decreased for more Zn content. The influence of the grain size on saturation magnetization and of Zn on Curie temperature was investigated for the Zn-Ni ferrite samples.
