摘要：
Structural and magnetic properties of CoFe2-xMoxO4 (x = 0, 0.04, 0.08, 0.12, 0.16, 0.2, and 0.3) nano ferrites synthesized by autocombustion method were investigated. X-ray powder diffraction patterns have confirmed the pure cubic crystalline phase of the synthesized nanoparticles. Magnetic properties were explored using vibrating sample magnetometry and Mossbauer spectroscopy. Both the crystallite size (D) and the saturation magnetization (M-s) decreased continuously with increasing Mo content. Bertaut method based on X-ray diffraction, infrared spectroscopy (IR) data, saturation magnetization and Mossbauer spectroscopy were used to suggest the cation distribution in tetrahedral (A) and octahedral [B] sites for the whole samples.
