Goncharov A.F., Muinov M.T., Uvarova T.G., Stishov S.M.
The Raman spectra of õ÷Á2óÉ30, single crystals (x =--6,25; 6,75; 7,0) were measured at pressures up to 22 GPa (35 GPafor χ = 6,25) at room temperature in nearly hydrostatic conditions. The frequency-volume curves for the most Raman-active fundamental vibrations were derived from the present data making use the previous high-pressure study of the equations of state of YBa2Cu3Ox compound.
