It was ascertained that the spectra of Ni3V2O8 does not sensitive to appearance of incommensurable magnetic order. The first principle calculation of phonon spectra FeTe was performed. New phenomenon was detected. It is dependence of phonon frequencies on magnetic ion spin state. Spin-phonon interaction constant were founded. Product Description popup.authors Гнезділов В.П.
