Galkin Physics and Engineering Institute of National Academy of Science of the Ukraine popup.description2 Enumeration of magnetic multi-k structures which lead to an appearance of electrodipole one-phonon absorption from the Brillouin zone boundaries has been done with help of symmetry criterium. The measurements of infrared absorption and Raman light scattering phonon spectra of Nd2CuO4, La2CuO4 and La1,775Sr0.225NiO4 were carried out. Program of phonon spectra calculations of R2CuO4 compounds was developed. Product Description popup.authors popup.nrat_date 2020-04-02 Close
