Abstract

CoMnxFe2-xO4 with x = 0; 0.10; 0.25; 0.40; 0.60 and 2.0 were prepared by low temperature combustion method. The samples were investigated using X-ray diffraction analysis at room temperature. All the synthesized samples exhibited XRD patterns specific for cubic spinel phase with a space group Fd3m. Infrared spectroscopic analysis, using KBr pellets in the range 400 - 4000 cm-1 was carried out using a FTIR 600Plus Fourier transform infrared spectrometer. The magnetic properties of samples have been characterized at room temperature using a vibrating sample magnetometer, the magnetic properties measurements demonstrate an increase of the saturation magnetization with the increase of Mn content..
