The samples were compacted by isostatic pressing and sintered at 1000°C for 36 h. The spectra of X-ray diffraction showed the MnxCu1- xFe2O4 ferrite with x=0.40 to x= 0.46 with compact structure spinel with cubic symmetry. Magnetic properties were investigated by vibrating magnetometer.The magnetic properties of samples were characterized by hysteresis measurements M versus H. The saturated magnetization of the MnxCu1-xFe2O4 ferrite samples is varied with the concentration of manganese. The samples with manganese concentration of x= 0.40 to 0.46 showed features typical hysteresis curve of soft magnetic materials. The magnetization of ferrites using vibrating sample magnetometer was performed at room temperature under an applied field of 15 kG and the hysteresis loops of the ferrite powders were obtained .The spinel structure of samples was characterized by X-ray powder diffraction (XRPD) using a diffractometer with Cu K? radiation.
