In this study Mn–Zn ferrite nanoparticles (Mn (1− x ) Zn x Fe 2 O 4 , 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 Mn 0.7 Zn 0.3 Fe 2 O 3 ferrite nanoparticles have the maximum saturation magnetization and that the initial susceptibility decreases with the increase in Zn concentration.
