Strain effects and thickness dependence of ferroelectric properties in epitaxial BiFeO3 thin films

Ma, Hua; Chen, Lang; Wang, Junling; Ma, Jan; Boey, Freddy Yin Chiang (2008)

A “misfit strain-temperature” phase diagram for BiFeO3 thin film was constructed based on the Landau–Devonshire theory with the mechanical substrate effect. It is found that the polarizatio ...
