Preparation, characterization and magnetic properties of nanocrystalline Ni-Zn ferrites

By P. U. Mahamuni and B. K.Chougule

Abstract

Nanocrystalline NixZn1-xFe2O4 ferrites (with x = 0.1,0.3,0.5,0.7,0.9) were synthesizes by sucrose process.The powders were sintered at 900 0C for 12 h to densify properly.The samples were characterized by XRD, TEM and IR spectroscopy. XRD confirms single phase spinel structure. The lattice constant increases with increase in Zn content. TEM reveals nanocrystalline nature of samples while IR absorption spectra  shows two prominent bands for characteristic A and B site vibrations. The magnetic properties were measured by using high field hysterisis loop tracer.

 

Key Words : Nanocrystalline ferrites, sucrose method, TEM, IR spectra, magnetic properties.
