Effect of Nickel Substitution on Structural and Magnetic Properties of Novel Polyol route Synthesized Cobalt Ferrite

Abstract

Nanocrystalline NixCo1-xFe2O4 (1.0 ≥ x ≥ 0) ferrites were prepared by polyol route. Formation of single phase cubic spinel structure for all the compositions was confirmed from their X-ray diffraction patterns. These ferrite samples existed as crystalline nanoparticles of about 10-20 nm size as observed from Transmission Electron Microscopy technique. The magnetic studies indicated that, the ferrimagnetic behavior increases with nickel substitution.
