Tailoring of structural, electrical and magnetic properties of BaCo2 W-type hexaferrites by doping with Zr-Mn binary mixtures for useful applications

► Zirconium ions preference is for fIV sublattice while Mn ions prefer 4fVI and 2b sublattices. ► Room temperature resistivity of up to 2.82×109 Ω cm is obtained for doped hexaferrites. ► High value of saturation magnetization (67.0 emu/g), remanent magnetization (34.7 emu/g) and coercivity (1861 Oe) make doped hexaferrites to be utilized as data processing devices.
