Complete solid solutions were formed in the system of (1 - x)Pb(Fe2,3W1/3)03-xPb(Col/zWl/z)O3. Crystallographic, dielectric, magnetic properties and Mossbauer spectra were measured for the system. It was concluded from our measurements that the com ounds in the range of 0.1 5 x 5 0.7 are ferroelectric-ferrimagnets, having the ordered arrangement of Fe3+, Co2+ a nd W6+ ions. Both dielectric and magnetic phase diagrams were proposed. The system and the variation of the magnetic Curie or Nee1 temperature, with the composition, was discussed, based on the hypotheses of Goodenough el al. and Gilleo. The shapes of the Mossbauer spectra were also discussed using our proposed model.
