Preparation and Magnetic Properties of BaFe12-2xCox-ySnxNiyO19 Particles

Abstract : BaFe12-2xCox-ySnxNiyO19 hexagonal-plated-shaped barium ferrite powders were prepared by chemical pricipitation and subsequent heat treatment to investigate the effects of Ni ion on the magnetic properties of the barium ferrite powders. Experimental results indicates that if the y value in the chemical formula is varied and the x value is maintained constant, i.e. the partial replacement of Co ion by Ni ion, the particle size and σ of the powders were reduced; furthermore, the Hc value of the powders would be maximized at a certain y value. If the x value is varied and maintained y=0.5x, the large the addition of (Cox/2Nix/2Snx) ions causes the more of a decrease in the σ value, Hc value, and curie temperature.
