Magnetically induced electronic ferroelectricity in half-doped manganites.
Using a joint approach of density functional theory and model calculations, we demonstrate that a prototypical charge ordered half-doped manganite La1/2Ca1/2MnO3 is multiferroic. The combination of a peculiar charge-orbital ordering and a tendency to form spin dimers breaks the inversion symmetry and leads to a ferroelectric ground state with a polarization up to several microC/cm2. The presenc...
متن کاملFirst-principles theory of magnetically induced ferroelectricity in TbMnO3
We study the polarization induced via spin-orbit interaction by a magnetic cycloidal order in orthorhombic TbMnO3 using first-principle methods. The case of magnetic spiral lying in the bc plane is analyzed, in which the pure electronic contribution to the polarization is shown to be small. We focus our attention on the lattice-mediated contribution, and study it’s dependence on the Coulomb int...
متن کاملMagnetically-induced ferroelectricity in the (ND4)2[FeCl5(D2O)] molecular compound
The number of magnetoelectric multiferroic materials reported to date is scarce, as magnetic structures that break inversion symmetry and induce an improper ferroelectric polarization typically arise through subtle competition between different magnetic interactions. The (NH4)2[FeCl5(H2O)] compound is a rare case where such improper ferroelectricity has been observed in a molecular material. We...
متن کاملMagnetically induced thermal rectification.
We consider far from equilibrium heat transport in chaotic billiard chains with noninteracting charged particles in the presence of nonuniform transverse magnetic field. If half of the chain is placed in a strong magnetic field, or if the strength of the magnetic field has a large gradient along the chain, heat current is shown to be asymmetric with respect to exchange of the temperatures of th...
متن کاملMagnetically Induced Plasma Rotation
The extensively studied and controversial question about the origin of the observed fast rotation for magnetically confined plasmas, in particular theta pinches, is briefly reviewed. It is shown that standard MHD equations predict the experimentally observed rotation. The effect is interpreted as a form of the Einstein-de Haas effect. The generally accepted continuum plasma reasoning which deni...
