Theoretical symmetry analysis of crystal and magnetic subsystems was performed too. Using symmetry arguments it was ascertained a special type of ferrimagnetic ground state which does not generate a spontaneous electric polarization. New lines of purely magnetic origin have been detected in the magnetically ordered state. A part of them are attributed as scattering on exchange magnons. Using this observation and further symmetry analysis the existing of strong Dzyaloshinskii-Moriya interaction in the Cu2OSeO3 has been argued. Product Description popup.authors Гнезділов В.П.
