Magnetostructural Effect in the Multiferroic BiFeO3-BiMnO3 Checkerboard from First Principles
arXiv:0906.3201 · doi:10.1103/PhysRevLett.104.037202
Abstract
Using first principles calculations, we present a magnetostructural effect in the BiFeO3-BiMnO3 nanocheckerboard that is not found in either bulk parent compound or in BiFeO3-BiMnO3 superlattices. We also demonstrate that the atomic-scale checkerboard has a multiferroic ground state with the desired properties of each constitutent material: polar and ferrimagnetic due to BiFeO3 and BiMnO3 respectively.
