Abstract

Co(1−x)MnyZnyFe2O4 (x = 0.9,0.5, 0.1 and y = 0.45, 0.25, 0.05.) nanoparticles of average crystalline size of 61 nm were prepared by chemical co-precipitation method. XRD, FTIR, SEM were utilized in order to study the effect of variation in the cobalt substitution and its impact on size and associated water content. The average crystalline size (DaveXR) of the particles was found to be decreased from 85 to 41 nm with the increase in cobalt concentration. Fourier transform infrared spectroscopy (FTIR) spectra of the Co(1−x)MnyZnyFe2O4 in the range 400–4000 cm−1 were reported. The spinel structure and the crystalline water adsorption of cobalt doped Mn-Zn nanoparticles were studied by using FTIR.KeywordsFerritesSpinelCo-precipitationCrystalline size
