In the present paper we study the effect of high hydrostatic pressure (up to 16 GPa) on the Raman spectrum of Lu 3 Al 5 O 12 single crystals. Lu 3 Al 5 O 12 belongs to the crystal family of rare earth garnets (Re 3 Al 2 (AlO 4 ) 3 , Re: Gd, Tb, Dy, Er, . . .). These materials crystallize with the bo

Raman spectra of the layered compound, antimony triiodide are reported for samples at ambient temperature and at pressures up to 16 GPa. Changes in the number of observed peaks and their wavenumbers, relative intensities and spectral linewidths are discussed. Evidence for reversible crystallographic
The pressure dependence of the Raman spectra of was investigated up to 15.5 GPa. The anti-ferrodistortive SrTiO 3 cubic-tetragonal phase transition (phonon condensation at the R point of the Brillouin zone) occurs at about 6 GPa. The strong, broad bands, present under ambient conditions, sharpen and
A high-pressure Raman study of BaCeO 3 was performed at room temperature. This perovskite compound undergoes two phase transitions at about 22 and 28 GPa. The increase in the number of bands is an indication that the symmetry is lowered and that the compound does not evolve towards the ideal cubic p
