Abstract In the systems of solid solutions (1−x)NaNbO3−x A0.5Bi0.5TiO3, where A is Li (I), Na(II), K(III), and Ag(IV), the concentration dependence of the temperature T m, corresponding to a maximum in the dielectric permittivity ε, is described by a curve with minimum. In systems II and IV, a “ break” is observed on the T m(x) dependences in the region of x≈0.2, and the compositions with x〈0.2 are characterized by anomalously large temperature hysteresis of ε(T) reaching 80–100 K. Some compositions of systems I and III have very diffuse peaks of ε(T) in the room temperature range, which is of interest from the standpoint of search for lead-free relaxer materials.
