Author affiliations

Abstract

Structural phase transition and spin reorientation of orthoferrites LaFeO3 epitaxially grown along the pseudocubic (001) direction are investigated based on first-principles calculation. In the process of the LaFeO3 film growth, two phases Pmc21(3) and P4mm with the larger ferroelectric are obtained. And spin reorientation transition happened which induced by strain from Γ4 to Γ2 about misfit strain 2.28% in c-ePbnm phase. The critical strain for observation of the Γ4–Γ2 transition in LaFeO3 is very small, which will be a great surprise for experimental worker.
