Evolution of the magnetic properties during the thermal treatment of barium hexaferrite precursors obtained by coprecipitation from barium ferrate (VI) solutions

The evolution of macroscopic magnetic properties of BaFe12O19 synthesized by a new chemical coprecipitation method are presented and discussed. Structural and magnetic properties were investigated by X-ray diffraction, scanning electronic microscopy and magnetic measurements on fine particles result...
