Abstract

Nickel zinc ferrite (NixZn1−xFe2O4 where x=0.1, 0.3, 0.5) nanoparticles were synthesized by chemical co-precipitation method. The doping effect of nickel ions on crystalline phase, size, particle size, and saturation magnetization (M S) are investigated. The XRD patterns confirm the single crystalline phase of the nanoparticles. The lattice parameter decreases with increase in Ni content and reduces lattice strain. HRTEM images reveal the crystalline nature of nanoparticles with size distribution in 10–30 nm range. The M-H curve exhibit the superparamagnetic nature of x=0.1 and x=0.3 samples and ferromagnetic nature for x=0.5 sample. Ms increases with rise in Ni2+ ions concentration. These ferrite nanoparticles are suitable for ferrofluids applications.
