摘要：

In order to study the influence of substitutions and of the ionic radii of B' ions on structure and phase transitions, we present some physical measurements and data on Pb2B'B"O-6 (B" = W, Nb, Mo) complex perovskite compounds. By Mn and Fe substitution for Mg in Pb2MgWO6 compound a change in lattice parameters and shift of antiferroelectric transition temperature is observed. It appears that in all three series of compounds a linear dependence between ferroelectric or antiferroelectric transition temperature and B' ionic radii is observed.
