Pure and (Co, Ti)-substituted (Ba, Sr)-hexaferrite particles have been prepared by modified coprecipitation and aerosol synthesis technique. The phase composition of the intermediate products and the crystallization process were investigated by DTA-TG, electron microscopy, vibrating sample magnetometry and Mossbauer spectroscopy analyses. The phenomena, connected with transition into superparamagnetic state for the particles of about 10 nm in size are investigated.
