Structure parameters and magnetic properties of Me2W1 cobalt-containing hexaferrite systems synthesized by the SHS method

Optimal conditions for synthesis of BaCo2–hZnhFe16O27 system hexaferrite powders fabricated using novel energy-saving technology of self-spreading high-temperature synthesis (SHS) with preliminary mechanical activation are determined. The phase composition and morphology of the synthesized materials are investigated by the method of x-ray structural and phase analysis. Values of specific saturation magnetization, crystal magnetic anisotropy field, spin reorientation transition temperature, and Curie’s temperature are determined based on static and dynamic measurements of the magnetic properties. Spectra of the magnetic permeability and dielectric permittivity are measured in the microwave range.
