Abstract

We investigate in the framework of Landau theory the distortion of the strain fields at the interface of two dissimilar ferroelastic oxides that undergo a structural cubic-to-tetragonal phase transition. Simple analytical solutions are derived for the dilatational and the deviatoric strains that are valid over the entire heterostructure. The solutions reveal that the dilatational strain exhibits compression close to the interface, which may in turn affect the electronic properties in that region.
