Abstract
Polycrystalline samples of SrMe2Fe16O27 (SrMe2-W) with Me2+=Zn, Co, Ni, Mn, Mg, Cu, and Sr2Zn2Fe28O46 (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.
