Structural Instability of Epitaxial (001) BiFeO3 Thin Films under Tensile Strain

We explore BiFeO3 under tensile strain using first-principles calculations. We find that the actual structures are more complex than what had been previously thought, and that there is a strong shear deformation type structural instability which modifies the properties. Specifically, we find that normal tensile strain leads to structural instabilities with a large induced shear deformation in (...

Strain-induced polarization rotation in epitaxial (001) BiFeO3 thin films.

Direct measurement of the remanent polarization of high quality (001)-oriented epitaxial BiFeO3 thin films shows a strong strain dependence, even larger than conventional (001)-oriented PbTiO3 films. Thermodynamic analysis reveals that a strain-induced polarization rotation mechanism is responsible for the large change in the out-of-plane polarization of (001) BiFeO3 with biaxial strain while t...

Tuning magnetic coupling in Sr2IrO4 thin films with epitaxial strain.

We report x-ray resonant magnetic scattering and resonant inelastic x-ray scattering studies of epitaxially strained Sr2IrO4 thin films. The films were grown on SrTiO3 and (LaAlO3)0.3(Sr2AlTaO6)0.7 substrates, under slight tensile and compressive strains, respectively. Although the films develop a magnetic structure reminiscent of bulk Sr2IrO4, the magnetic correlations are extremely anisotropi...

Strain-induced symmetry reduction of epitaxial La0.67Sr0.33MnO3 films

Introduction Due to spin, lattice and orbital coupling, manganese-based La1-xSrxMnO3 (LSMO) compounds exhibit unusual physical properties, such as colossal magnetoresistance and almost total spin polarization (95% at 4 K) at the composition x = 0.33 [1]. Thus, La0.67Sr0.33MnO3 has significant potential for applications in spintronic devices such as magnetic field sensors, networked environmenta...
