Ferroelectrics have a spontaneous electrical polarization that is arranged into domains and
can be reversed by an externally-applied field. This high versatility makes them useful in …

Polar discontinuities, as well as compositional and structural changes at oxide interfaces
can give rise to a large variety of electronic and ionic phenomena. In contrast to earlier work …

In this work, spin density functional theory calculations are employed to obtain the exchange
interactions in hexagonal YMnO 3 and LuMnO 3 multiferroic compounds, which have been a …

The atomic nature of topologically protected ferroelectric (FE) walls in hexagonal ReMnO 3
oxides (R: Sc, Y, Er, Ho, Yb, Lu) creates an interesting playground to study effects of defects …

Research on topological defects in hexagonal manganites exposed uncovered properties of
topologically protected domains and domain walls. Topological defects of h-REMnO3 oxides …
