M-type hexagonal barium ferrites Ba(M x Ti x)Fe 12−2x O 19 (M=Co or Ti, x=0-0.5) are synthesized by chemical route. Experimental values of the anisotropy fields H K are extracted from microwave measurements. It is shown that H K values are very close to the higher switching field. Results show that the shift through lower values both for H K and the switching field distributions are the largest for CoTi substitutions. A qualitative analysis based on the cations occupation sites is proposed.
