Abstract
This paper reports the first single-crystal Raman spectra of substituted ba rium hexaferrites, BaFe12-2xMexCoxO19 (Me = Ir, Ti). The spectra were inves tigated in the 200-900 cm(-1) range and are discussed in comparison with un substituted barium hexaferrite. Emphasis was placed on the different factor s influencing the Raman spectra of substituted barium hexaferrites, namely the mass of the substituting cation, the ionic radius and charge and the or dering on the five distinct iron sites.
