Pressure-induced phase transition of La₂Zr₂O₇ and La_0.5Gd_1.5Zr₂O₇ pyrochlore

Abstract

In situ high-pressure experiments on La₂Zr₂O₇ and La_0.5Gd_1.5Zr₂O₇ have been carried out at up to approximately 40 GPa using synchrotron X-ray diffraction and Raman spectroscopy combined with a diamond anvil cell technique.
