Supplementary materials from Pressure-induced order–disorder transition in Gd_1.5Ce_0.5Ti₂O₇ pyrochlore

Abstract

This ESM file has three supplementary figures.Fig. S1 is the selected XRD patterns of Gd1.5Ce0.5Ti2O7 under different pressures in run2. ☆ belong to Argon's reflections. Fig.S2 is the a-axial length a(Å) as a liner function of pressure. The slope change is observed as 6.5 GPa and 13 GPa, respectively. Fig. S3 is the Le Bail refinement of Gd1.5Ce0.5Ti2O7 at various pressures. a)-c) are patterns from run1, with silicone oil as pressure medium. d)-f) are patterns from run2, with Argon as the pressure medium. Magenta bar are reflections of pyrochlore structure and green bar belongs to pressure-induced solidified Argon.
