Magnetic and morphological characterization of SrMe/sub 2/-W and SrZn-X hexaferrites prepared by chemical coprecipitation method

Polycrystalline samples of SrMe/sub 2/Fe/sub 16/O/sub 27/ (SrMe/sub 2-/W) with Me/sup 2+/=Zn, Co, Ni, Mn, Mg, Cu, and Sr/sub 2/Zn/sub 2/Fe/sub 28/O/sub 46/ (SrZn-X) hexagonal ferrites have been prepared by the chemical coprecipitation method. The main steps of W- and X-phase formation have been evidenced by means of Mossbauer spectroscopy, X-ray diffraction techniques, scanning electron microscopy, and thermal magnetic analysis. The intrinsic and extrinsic magnetic properties of the samples (saturation magnetization, anisotropy field, coercive field, and Curie temperature) and the morphological characterization are reported.<
