ABSTRACT: In this study Mn–Zn ferrite nanoparticles (Mn(1−x)Zn
x
Fe2O4, x=0, 0.3 and 0.5) were produced by a chemical co-precipitation method. The structure and size of the Mn–Zn ferrite nanoparticles
were characterized using X-ray diffraction (XRD) and Transmission electron microscopy (TEM). Results show that the ferrite
nanoparticles have the spinel structure. It was found that the size of Mn–Zn ferrite nanoparticles decreases by increasing
of the Zn concentration. The magnetic properties of Mn–Zn ferrite nanoparticles were investigated with a vibrational sample
magnetometer (VSM) and it was observed that Mn0.7Zn0.3Fe2O3 ferrite nanoparticles have the maximum saturation magnetization and that the initial susceptibility decreases with the increase
in Zn concentration.
