  • Abstract
    The effect of partial substitutions of Zn2+ ions with Cu2+ and Co2+ ions in Ni0.33Zn0.67Fe2O4 ferrite were investigated on magnetic properties. Fine particles of Ni0.33Zn0.67-xMex, ferrites with Me = Cu2+/Co2+ were prepared by the self-propagated combustion method. Variation of temperature dependences of the magnetic susceptibility χ(T) with composition is discussed and possible magnetic mechanism is investigated. Grain size is one of the factors determining the magnetic properties of ferrite materials. The chemical and structural changes of ferrite during substitution treatment are analyzed also using Mossbauer spectrum and SEM. Initial permeability varies with ion content x in ferrite materials, which is attributed to the variation of grain size.
