- Abstract
CoMgFe O nanoparticles with x values 0, 0.5, and 1 were synthesized using a microwave-assisted combustion method and subsequent heat treatment. The stoichiometric mixture of Co(NO)⋅ 6HO, Fe(NO)⋅ 9HO, Zn(NO)⋅ 6HO, and urea was used as the fuel additive. The structural, morphological, and magnetic properties of synthesized nanoparticles were then investigated using X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and vibrating sample magnetometer analysis techniques. The mean crystal size of the synthesized samples was about 32 nm based on Scherrer's formula. The saturation magnetizations ( M ) were also 59, 27, and 28 emu/g for samples with x values 0, 0.5, and 1, respectively. Results showed direct changes in coercivity and remanent magnetization parameters by increasing the Co content, which can be attributed to the anisotropic nature of cobalt.
