| Description |
Nanocrystalline nickel ferrite with different concentration of Ni and Zn (NixZn1−xFe2O4 where x=0.1, 0.3,
0.5) were synthesized using chemical co-precipitation method. The effect of doping ion concentration on
physical properties like crystalline phase, crystallite size, particle size, and saturation magnetization are
investigated. The X-ray diffraction pattern confirms the synthesis of single crystalline NixZn1−xFe2O4
nanoparticles. The lattice parameter decreases with increase Ni content resulting in reduction of lattice
strain. HRTEM images revealed that the as-prepared nanoparticles were crystalline with particle size
distribution in 10–30 nm range. The saturation magnetization show the superparamagnetic nature of sample
for x=0.1 and x=0.3 whereas for x=0.5, the material is ferromagnetic. The saturation magnetization value
is 23.95 emu/gm for Ni0.1Zn0.9Fe2O4 sample and it increases with increase in Ni content.
