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…
