Phase Transitions in BiFeO3–ANbO3 (A = Na, K) Solid Solutions

Some of the known binary ABO3perovskites with ferro- (FE) or antiferroelectric (AFE) at [Formula: see text] and different magnetic phase transitions (PT): ferro-and antiferromagnetic at [Formula: see text] and also some of their solid solutions are considered. Some correlations between their FE or AFE and/or magnetic PTs temperatures, on the one hand, and their interatomic bond [Formula: see text]–O strains, on the other hand, have been constructed. It is shown that in the plotted diagrams these temperatures change with a change in [Formula: see text] values as follows: classical FEs are followed by multiferroics, starting with BiFeO3 and ending with YVO3, followed by classical AFEs. At the same time, the temperatures [Formula: see text] and [Formula: see text] experience maxima at the corresponding points for BiFeO3, then quickly decrease, and the difference between them, [Formula: see text]-[Formula: see text], basically also decreases, slightly increasing along the way to the point EuTiO3. which made it possible to systematize these [Formula: see text] and [Formula: see text].
