Pressure-induced amorphization of La1/3NbO3

► La1/3NbO3 has been studied under pressure by synchrotron XRD and Raman spectroscopy. ► La1/3NbO3 undergoes irreversible pressure induced amorphization at ~ 14.5 GPa. ► Upon full decompression the XRD pattern remains amorphous. ► However, part of the Raman spectrum reappears, and new Raman peaks become active.
