Structural and magnetic properties of CuxMg0.5−xZn0.5Fe2O4 (x = 0-0.5) particles

Several investigators have studied the magnetic and electrical properties of Mg-Zn ferrites by partially substituting Mg with Cu ions to be fabricated by different methods. However there is still some lack in magnetic characteristics of this type ferrite, particularly magnetic susceptibility of Mg-Cu-Zn ferrite is not widely studied. With this view in mind the present paper premise deals with the formation and magnetic properties of CuxMg0.5−xZn0.5Fe2O4 (x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5) in powder configuration in micron and nanosized range by sol-gel method. The magnetic susceptibility versus applied field and temperature was investigated for micron and nanosized Mg-Cu-Zn ferrite respectively. The role of copper cations on the saturation magnetization, coercivity, grain growth and phase formation of Mg-Zn ferrite is also evaluated.
