Structural domain walls in polar hexagonal manganites [PDF]
Nature Communications, 2013 We present a microscopic first-principles study of the neutral structural domain walls (DWs) in the multiferroic hexagonal manganites, which have been shown to exhibit cross-couplings between ferroelectricity and struc- tural antiphase. We find that, in contradiction with previously proposed models, the interlocked antiphase- ferroelectric domain walls
