Mean-field theory of the electromagnon resonance
Pavel A. Andreev, Mariya Iv. Trukhanova
We present the analytical theory of the electromagnon resonance for the multiferroics of spin origin. We consider the spin density evolution under the influence of magnetoelectric…
Electric polarization evolution equation for antiferromagnetic multiferroics with the polarization proportional to the scalar product of the spins
Pavel A. Andreev, Mariya Iv. Trukhanova
The spin current model of electric polarization of multiferroics is justified via the quantum hydrodynamic method and the mean-field part of the spin-orbit interaction. The spin cu…
Polarization evolution equation for the exchange-strictionally formed II-type multiferroic materials
Pavel A. Andreev, Mariya Iv. Trukhanova
The multiferroics are the materials, where single cell of a magnetically order crystal forms an electric dipole moment. We derive equation for the evolution of the macroscopic dens…
A new quantum hydrodynamic description of ferroelectricity in spiral magnets
Mariya Iv. Trukhanova, Pavel A. Andreev, Yuri N. Obukhov
The strong coupling between magnetism and ferroelectricity was found in rare earth manganites, where the electric polarization could be induced by special magnetic ordering. There…
A new microscopic representation of the spin dynamics in quantum systems with the Coulomb exchange interactions
Mariya Iv. Trukhanova, Pavel Andreev
There is a version of the Landau-Lifshitz equation that takes into account the Coulomb exchange interactions between atoms, expressed by the term .…
