Unfolding of vortices into topological stripes in a multiferroic material
Xueyun Wang, Maxim Mostovoy, Myung-Geun Han +4
Multiferroic hexagonal RMnO3 (R=rare earths) crystals exhibit dense networks of vortex lines at which six domain walls merge. While the domain walls can be readily moved with an ap…

Ferroelectric switching dynamics of topological vortex domains in a hexagonal manganite
Myung-Geun Han, Yimei Zhu, Lijun Wu +6
Field-induced switching of ferroelectric domains with a topological vortex configuration is studied by atomic imaging and electrical biasing in an electron microscope, revealing th…

Atomic-scale structure of the SrTiO3(001)-c(6x2) reconstruction: Experiments and first-principles calculations
C. H. Lanier, A. van de Walle, N. Erdman +7
The c(6x2) is a reconstruction of the SrTiO3(001) surface that is formed between 1050-1100oC in oxidizing annealing conditions. This work proposes a model for the atomic structure…
