Flop of Electric Polarization Driven by the Flop of the Mn Spin Cycloid in Multiferroic TbMnO3
N. Aliouane,Karin Schmalzl,D. Senff,A. Maljuk,Karel Prokes,Markus Braden,Dimitri N. Argyriou +6 more
TL;DR: Using in-field single-crystal neutron diffraction, the magnetic structure of TbMnO(3) in the high field P parallel a phase is determined and it is established that the ferroelectric polarization arises from a cycloidal Mn spin ordering, with spins rotating in the ab plane.

Band-filling effect on magnetic anisotropy using a Green's function method
Liqin Ke,Mark van Schilfgaarde +1 more
TL;DR: In this article, an analytical model to describe the magnetocrystalline anisotropy energy (MAE) in solids as a function of band filling is presented. But the model is based on second-order perturbation theory, which makes it possible to decompose the MAE into a sum of transitions between occupied and unoccupied pairs.
