Pressure-dependent X-ray diffraction of the multiferroics RMnO.

The room-temperature structural properties of the RMnO multiferroics have been investigated under pressure, using powder X-ray scattering and density functional theory (DFT) calculations. It was possible to determine the lattice parameters and the main atomic positions as a function of pressure. Good agreement was observed between the X-ray and DFT results for most of the determined crystallographic data.
