High pressure Raman study and phase transitions of KIO3 non-linear optical single crystals
Potassium iodate KIO3 single crystal samples have been studied under pressure up to 35 GPa at room temperature. Drastic spectral changes and phase transitions were observed. The first phase transition occurs at 5. 0 GPa ...
Pressure-induced phase transitions of KTiOAsO4 by Raman spectroscopy
Potassium titanyl orthoarsenate KTiOAsO4 has been studied by Raman spectroscopy up to 16 GPa. Three first-order pressure-induced phase transitions are inferred from Raman data. The first phase transition takes place at 3. ...
