Abstract
Hexagonal ferrites in the BaO-Fe2O3- CoO system have the M, Y, Z, W and S structures. BaFe12−x CO x O19−x prepared by the glass synthesis method crystallizes with the M structure but forx > O a few CoFe2O4 (S) crystallizes at first and then is located at the core of the recovered platelets of hexaferrite M. BaFe16− x CO2 +x O27-x F x prepared in the saure way has not the W structure but is a mixture of cobalt doped M and S.
