Abstract in another language

The structural and vibrational properties of the multiferroics YMnO3 and LuMnO3 have been studied by means of the x-ray diffraction and Raman spectroscopy at high pressures up to 29.3 and 31.2 GPa, respectively. The initial hexagonal structure with space group P6 3 cm of both compounds remains unchanged in the entire pressure range. The anisotropic baric behaviors of lattice parameters and vibration modes of studied compounds were observed. The structural mechanisms of those phenomena are discussed.
