Exploring the compression behavior of HP-BiNbO4 under high pressure |
(color online) The x-ray diffraction and Rietveld refinement patterns of HP-BiNbO4 about 1 GPa. (a) The HP-BiNbO4 sample based on Sm2Sn2O7. (b) The HP-BiNbO4 sample based on Dy3NbO7. Empty circle: observed curve; red line: calculated curve; green short vertical lines: all possible Bragg positions; bottom line: difference curve. |
