【摘要】We report the synthesis of Co2＋ substituted Mg-Cu-Zn ferrite via citrate gel combustionprocess and thereby its structural, transport, and magnetic properties for the use in electromagneticenergy absorption application. The polycrystalline ferrite system is investigated by

interplay

ofstoichiometric

composition

with

Mg0.25-

xCoxCu0.25Zn0.5Fe2O4 （0 ≤ x ≤ 0.25）. Structural investigationsusing X-ray diffraction （XRD） and selected area electron diffraction （SAED） reveal the formation ofspinel structure with linear growth of lattice constant due to Co2＋ substitution. The microstructuralanalysis （TEM and SEM） depicts the dense microstructure with the average grain size of 0.42-1.25 μm. The elemental analysis （EDS） confirms the elemental composition of the as-prepared ferritewith respect to the initial concentrations of the synthetic composition used. The observed variations ininitial permeability （pi） and magnetic moment （ nB ） are explained based on deviation in saturationmagnetization （Ms ）,

anisotropy constant （K1 ）, density values, and exchange interaction. Thetemperature

dependence

of

DC

resistivity

confirms

the

semiconducting behavior of the as-preparedferrite material, with an increase in the DC resistivity by an incorporation of cobalt. Furthermore, theeffects of adding Co2＋ on the Curie temperature, frequency dependent dielectric properties of theferrite material are also discussed. 【总页数】11页(P.207-217) 【
