Abstract
This paper presents a study of BaFe12-2xTixCoxO19, where the substitution-i nduced magnetic anisotropy change has been investigated through magnetic me asurements and single-crystal neutron diffraction. The study shows that the magnetic structures of BaFe12-2xTxCoxO19 change drastically when the tempe rature and the substitution rate are altered. It is proposed that an antife rromagnetic mode in doped Ba-hexaferrites is one of the key elements to und erstand the origin of their promising microwave properties. (C) 2001 Elsevi er Science B.V.
