摘要：

The modified coprecipitation method has been shown to be suitable for preparing BaFe2y-2xCoxTixO19 powder with narrow particle size distribution (50-80 nm). The phase composition of the intermediate products during the synthesis has been investigated by DTA, TG, X-ray analysis and Mossbauer spectroscopy. The dependence of the dc measured specific magnetization and coercivity on the Ti-Co content and annealing temperature is presented.
