Figure 1
Powder neutron diffraction pattern obtained from CrF3 at 8.56 GPa. The crosses and the solid line represent the measured and calculated patterns, respectively. The lower curve shows the difference between observed and calculated intensities. From the bottom to the top the vertical tick marks shown represent the Bragg reflection positions for CrF3, WC and Ni, respectively. The weak contributions to the pattern from WC and Ni arise from the anvils of the pressure cell. |
