Dielectric response of the antiferromagnetic multiferroics with cycloidal equilibrium for the polarization related to the noncollinear spins
Pavel A. Andreev
Linear dynamics of the small amplitude perturbations in the antiferromagnetic multiferroics is analytically considered. Equilibrium state in the considered regime is assumed to be…
Topological charge, helicity and vorticity conservation and the reverse spin-current model in the II-nd type multifferoics
Pavel A. Andreev
The topological charge and its density are related to the spin vorticity, while the spin vorticity is a part of full vorticity of the medium. The full vorticity is related to an in…
Analytical analysis of the spin wave dispersion in the cycloidal spin structures under the influence of magneto-electric coupling
Pavel A. Andreev
Spin waves and coupling of the spin waves with electromagnetic waves are considered in the multiferroic materials with the electric dipole moment proportional to the scalar product…
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…
Regimes of optical transparency and instabilities of collinear dielectric ferromagnetic materials in the presence of the dynamic magnetoelectric effect
Pavel A. Andreev
The contribution of the polarization associated with the noncollinear parts of spins in the dielectric permeability tensor of multiferroic materials is considered. As the equilibri…
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…
