Coupling and competition between ferroelectricity, magnetism, strain and oxygen vacancies in AMnO3 perovskites
Astrid Marthinsen, Carina Faber, Ulrich Aschauer +2
We use first-principles calculations based on density functional theory to investigate the interplay between oxygen vacancies, A-site cation size / tolerance factor, epitaxial stra…
Interplay between strain, defect charge state and functionality in complex oxides
Ulrich Aschauer, Nicola A. Spaldin
We use first-principles calculations to investigate the interplay between strain and the charge state of point defect impurities in complex oxides. Our work is motivated by recent…
Strain-induced structural instability in FeRh
Ulrich Aschauer, Roisin Braddell, Sonia A. Brechbühl +2
We perform density functional calculations to investigate the structure of the inter-metallic alloy FeRh under epitaxial strain. Bulk FeRh exhibits a metamagnetic transition from a…
