摘      要：We report the synthesis of Co^(2+)substituted Mg–Cu–Zn ferrite via citrate gel combustion process and thereby its structural,transport,and magnetic properties for the use in electromagnetic energy absorption *** polycrystalline ferrite system is investigated by interplay of stoichiometric composition with Mg_(0.25–x)Co_x Cu_(0.25)Zn_(0.5)Fe_2O_4(0≤x≤0.25).Structural investigations using X-ray diffraction(XRD)and selected area electron diffraction(SAED)reveal the formation of spinel structure with linear growth of lattice constant due to Co^(2+)*** microstructural analysis(TEM and SEM)depicts the dense microstructure with the average grain size of 0.42–1.25μ*** elemental analysis(EDS)confirms the elemental composition of the as-prepared ferrite with respect to the initial concentrations of the synthetic composition *** observed variations in initial permeability(μ_i)and magnetic moment(_Bn)are explained based on deviation in saturation magnetization(M_s),anisotropy constant(_1K),density values,and exchange *** temperature dependence of DC resistivity confirms the semiconducting behavior of the as-prepared ferrite material,with an increase in the DC resistivity by an incorporation of ***,the effects of adding Co^(2+)on the Curie temperature,frequency dependent dielectric properties of the ferrite material are also discussed.
