Abstract
The barium hexaferrites of M-type BaFe12−2x (Co, Ni) x Zr x O19 were synthesized by citrate precursor method in 0.0≤x≤0.6 range. For comparison, Ni–Zr compounds were also prepared by mechanical milling. Mössbauer measurements show that of Zr4+ ions have preference for 2b and 2a+4f 1 sites whereas Co2+ ions prefer 4f 2 and 12k positions. Different occupations were observed on Ni–Zr substitutions. The temperature coefficient of the coercivity, dH c /dT, was nearby to zero (0.01 kA/m°C) for the Co–Zr substitutes and positive for the rest of the samples. A fast reduction of coercivity H c with the increase in substitution level (370 to 150 kA/m) were underwent for all (Co, Ni)–Zr mixtures.
