Abstract

It was found that complete solid solutions are formed in the systems of Pb(Fe_2/3W_1/3)O₃-Pb(Mg_1/3Ta_2/3)O₃andPb(MgW)_1/2O₃-Pb(FeTa)_1/2O₃. Pb(Fe_2/3W_1/3)O₃and Pb(Mg_1/3Ta_2/3)O₃are disordered perovskite type ferroelectrics, nevertheless the ordered arrangement of ions in the octahedral positions is formed to some degree in a certain region of intermediate composition. In the case of Pb(MgW)_1/2O₃-Pb(FeTa)_1/2O₃, the state changes from antiferro-to ferro-electric at about 70 mole percent of Pb(FeTa)_1/2O₃. The X-ray intensity of superlattice reflections was analyzed based on two different models. To confirm the ferro- or antiferro-electric behavior, the permittivity was measured in Pb(MgW)_1/2O₃-Pb(FeTa)_1/2O₃system under applying d.c. bias field, and forced transition from antiferro to ferro-electric state was observed to occur in the biasing cycle.
