In this researcher, the MnxFe0.7-xZn0.3Fe2O4 ferrite nanoparticles prepared by co-precipitation method. In these compositions the value of x varies from 0 to 0.7. Structural and magnetic properties of synthesized powder were characterized by X-ray diffraction XRD, Far-Infrared spectroscopy Far-FTIR, Transmission Electron Microscopy TEM and vibration sample magnetometer VSM. The XRD results show that all of the samples have single phase spinel structure. The average crystallite size estimated of about 12 to 7 nm, using Scherrer´s formula. The Far-FTIR measurements show, two frequency bonds within the rang 300 to 600 cm-1 indicate the presence of cation-anion interactions in the octahedral and tetrahedral sites, respectively.Also Transmission Electron Microscope images show particles size uniform distribution. The VSM results show that the saturation magnetization for all the samples decrease by increasing the manganese content.
