Some of the known binary ABO3perovskites with ferro- (FE) or antiferroelectric (AFE) at and different magnetic phase transitions (PT): ferro-and antiferromagnetic at 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 –O strains, on the other hand, have been constructed. It is shown that in the plotted diagrams these temperatures change with a change in 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 and experience maxima at the corresponding points for BiFeO3, then quickly decrease, and the difference between them, -, basically also decreases, slightly increasing along the way to the point EuTiO3. which made it possible to systematize these and .Some of the known binary ABO3perovskites with ferro- (FE) or antiferroelectric (AFE) at and different magnetic phase transitions (PT): ferro-and antiferromagnetic at and also some of their solid solutions are considered.
