High-pressure Raman study of MgV2O6 synthesized at high pressure and high temperature
A new structural phase of MgV2O6 was obtained by a high-pressure, high-temperature （HPHT） synthesis method. The new phase was investigated by the Rietveld analysis of X-ray powder diffraction data, showing space group Pbcn （No. 60） symmetry and a = 13.6113（6）A （1A =0.1 nm）, b = 5.5809（1）A, c = 4.856...

| Summary: | A new structural phase of MgV2O6 was obtained by a high-pressure, high-temperature （HPHT） synthesis method. The new phase was investigated by the Rietveld analysis of X-ray powder diffraction data, showing space group Pbcn （No. 60） symmetry and a = 13.6113（6）A （1A =0.1 nm）, b = 5.5809（1）A, c = 4.8566（3）A, V = 368.93（2）A3 （Z = 4）. High pressure behavior was studied by Raman spectroscopy at room temperature. Under 22.5 GPa, there was no sign of a structural phase transition in the spectra, demonstrating stability of the HPHT phase up to the highest pressure. |
