Multiferroicity induced by dislocated spin-density waves.
We uncover a new pathway towards multiferroicity, showing how magnetism can drive ferroelectricity without relying on inversion symmetry breaking of the magnetic ordering. Our free-energy analysis demonstrates that any commensurate spin-density-wave ordering with a phase dislocation, even if it is collinear, gives rise to an electric polarization. Because of the dislocation, the electronic and ...

Trie Field Induced Spin Density Waves (FISDWS) found in organic conductors represent a unique serres of transitions which meld trie one-dimensional physics of trie Peierls instability with trie two-dimensional physics of the Quantum Hall Elfect. This
متن کاملFerroelectricity induced by acentric spin-density waves in YMn2O5.
The commensurate and incommensurate magnetic structures of the magnetoelectric system YMn2O5, as determined from neutron diffraction, were found to be spin-density waves lacking a global center of symmetry. We propose a model, based on a simple magnetoelastic coupling to the lattice, which enables us to predict the polarization based entirely on the observed magnetic structure. Our data accurat...
