Stress-induced R-MA-MC-T symmetry changes in BiFeO3 films
J. H. Nam, H. S. Kim, A. J. Hatt +2
The recent discovery of a stress-induced structural phase transition in the single-component perovskite BiFeO3 has revived interest in this lead-free ferroelectric. The coexistence…
Strain-induced isosymmetric phase transition in BiFeO3
A. J. Hatt, N. A. Spaldin, C. Ederer
We calculate the effect of epitaxial strain on the structure and properties of multiferroic bismuth ferrite, BiFeO3, using first-principles density functional theory. We find that,…
Structural phases of strained LaAlO3 driven by octahedral tilt instabilities
Alison J. Hatt, Nicola A. Spaldin
We investigate the effect of epitaxial strain on [001]-oriented LaAlO3 using first-principles density functional calculations. We find a series of structural phase transitions betw…
Tri-layer superlattices: A route to magnetoelectric multiferroics?
Alison J. Hatt, Nicola A. Spaldin
We explore computationally the formation of tri-layer superlattices as an alternative approach for combining ferroelectricity with magnetism to form magnetoelectric multiferroics.…
