Abstract :
An aerosol technique and pyrolysis of a mixture of cobalt-nickel-zinc-magnesium and iron nitrates with a fixed stoichiometric composition are used to prepare submicron spherical particles of Co substituted ferrite powders with a spinel-type structure. The magnetic properties are studied using vibrating sample magnetometry (VSM) and ferrimagnetic resonance (FMR). Important parameters such as saturation magnetization, FMR linewidth, and spectroscopic splitting factor are taken into analysis
