The M?ssbauer spectra for the M-, W- and X-type hexagonal barium ferrites were measured. We obtained the M?ssbauer spectra parameters of the M- and W-type ferrites, using the method of trial and error of a number of superposed six-line Lorentzian spectra with experimental spectra. In crystallographic consideration the X-type ferrites may by regarded as a superposition of M- and W-type. Then we obtained eleven six-line sub-spectra of the X-type with good fitting of experimental data.
