It is shown theoretically that a giant magnetoelectric susceptibility exceeding ${10}^{\ensuremath{-}6}\text{ }\text{s}/\text{m}$ may be achieved in the ferromagnetic/ferroelectric epitaxial systems via the magnetization rotation induced by an electric field applied to the substrate. The predicted magnetoelectric anomaly results from the strain-driven spin reorientation transitions in ferromagnetic films, which take place at experimentally accessible misfit strains in ${\text{CoFe}}_{2}{\text{O…

TLDR
The existence of strain-induced ferroelectric order in quantum paraelectric KTaO3 is demonstrated by combining experimental investigations of epitaxial K TaO3 films and density-functional-theory calculations, and it is suggested that a region of short-range polar order might appear in the strain-temperature phase diagrams.
