The pressure dependences at room temperature of the translational lattice modes and of the u2 and u., internal bending modes of the ReO; ion in solid NH,ReO, are reported. There is no evidence of any phase transition up to a pressure of 15 kilobar. The pressure coefficients of the translational mode

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
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
