Type: article

Abstract: The known multiferroics (MFs)-ternary oxides with perovskite-type structure [Formula: see text] that undergo successive phase transitions (PTs), ferroelectric (FE) or antiferroelectric (AFE) — at the Curie temperature, [Formula: see text], and ferromagnetic (FM), antiferromagnetic (AFM) or ferrimagnetic at the Néel temperature, [Formula: see text] —and classical FEs and AFEs are considered. The dependences of the [Formula: see text], [Formula: see text] on the interatomic bond A–O strains in their perovskite structures have been constructed. On constructed dependencies, some ternary MFs are discovered, which have comparatively high temperatures of first FE or AFE and second magnetic PTs but their difference [Formula: see text]–[Formula: see text] values are high comparatively with the binary MFs.
