  • Abstract
    The hexagonal ferrite system (TiCu)Ni2W is of interest because it has a high internal field and potential millimeter-wave uses. The chemical formula of the sample studied is BaNi2Fe16-2x(TiCu)xO27 with x=0, 1, 2, and 3. Experimental results show that with increasing (TiCu) substitution the lattice constants a and c increase slightly, whereas the room-temperature saturation magnetization, the Curie point, and the anisotropic magnetic field are decreased. Room-temperature Mossbauer spectra are fitted with five subsets representing five magnetic sublattices, and the Mossbauer parameters are obtained. The hyperfine field of the magnetic sublattices is reduced with increasing (TiCu) content by different degrees; a small amount of paramagnetic phase appears at x=3. The experimental results are discussed in terms of ferrite physics
