Mn–Ce–Fe–O nanopowder was prepared by evaporation method. The results of XRD clarifying the samples are having a nanosized particles in the range ∼38–54 nm. SEM was also used to characterize the microstructure of the products. The nanostructure and particle size are confirmed by TEM. The magnetic properties of Mn–Ce–Fe–O system were measured at room temperature by using vibrating sample magnetometer (VSM). It is found that both remnant magnetization (Mr) and saturation magnetization (Ms) decrease with increasing the annealing temperature due to the decomposition of the system. The high value of saturation magnetization (Ms = 48.47 emu/g) and remnant magnetization (Mr = 20.27 emu/g) were obtained only for the asburnt sample not for annealed samples. The compositional analysis of Mn–Ce–Fe–O system was observed by energy-dispersive detection X-Ray spectra (EDXS).
