Abstract
The calcinations temperature is one of the important process parameter which influences the changes of magnetic properties in ferrites. This study provide better understanding of the influence of calcination temperatures on the magnetic properties of Nickel Zinc ferrite consequently enable to tailor the magnetic properties of Nickel Zinc ferrite for specific application. Magnetic nanoparticles of Nickel Zinc ferritewere synthesized by sol-gel technique. Their crystallite size and the influence of calcinations temperature on magnetic properties were investigated by using X-Ray Diffraction (XRD) and Vibrating Sample Magnetometer (VSM). XRD results showed that the crystallization of the Nickel Zinc ferriteincreased as the calcination temperature increased. The results showed that single phase of Nickel Zinc ferritesamples can be obtained at various calcination temperatures from 800 to 1100°C. All Nickel Zinc ferritesamples exhibited ferrimagnetic behavior. VSM results showed that the saturation magnetization and coercivity values strongly influenced by the calcination temperature.
Highlights
Nickel Zinc (NiZn) ferrite is a ferrimagnetic materials which are widely used in electronic devices such as EMI suppressor and electromagnetic wave absorber due to their low initial permeability

Summary
Nickel Zinc (NiZn) ferrite is a ferrimagnetic materials which are widely used in electronic devices such as EMI suppressor and electromagnetic wave absorber due to their low initial permeability. Magnetic properties of NiZn are from the magnetic ions (Fe3+) located in tetrahedral and octahedral coordinated sites and their interaction with surrounding oxygen ions. These oxygen ions influence the irons in different sites. It was found that the permeability of ferrite increase as the sintering temperatures increases.

Sol-gel technique is one of the well-known techniques to prepare the nanoparticles (Pozo Lopez et al, 2012). Ni0.75Zn0.25Fe2O4 nanoparticles were synthesized using Sol-gel Technique and their magnetic properties at different calcinations temperature were studied
