Non collinear magnetism and single ion anisotropy in multiferroic perovskites
Carlo Weingart, Nicola Spaldin, Eric Bousquet
The link between the crystal distortions of the perovskite structure and the magnetic exchange interaction, the single-ion anisotropy (SIA) and the Dzyaloshinsky-Moriya (DM) intera…
Incipient ferroelectricity in 2.3% tensile-strained CaMnO3 films
T. Günter, E. Bousquet, A. David +4
Epitaxial CaMnO3 films grown with 2.3% tensile strain on (001)-oriented LaAlO3 substrates are found to be incipiently ferroelectric below 25 K. Optical second harmonic generation (…
First-principles study of the ferroelectric Aurivillius phase Bi2WO6
Hania Djani, Eric Bousquet, Abdelhafid Kellou +1
In order to better understand the reconstructive ferroelectric-paraelectric transition of Bi2WO6, which is unusual within the Aurivillius family of compounds, we performed first pr…
