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
## Abstract Highβpressure Raman spectra of fullerite, a solid form of C~60~, were measured at pressures up to 4 GPa and room temperature. A change of slope (d__v__/d__P__) of the frequencyβpressure plots for the __A__~g~ pentagonal pinch mode and the __A__~g~ breathing mode was observed at 1.3 GPa,
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
