Figure 2
Lattice parameters a and c (a) and the relative volume V/Vo (b) plotted as a function of pressure. The solid curve for the relative volume represents a fit to the third-order Birch–Murnaghan equation of state with bulk modulus [B_o] = 14 (1) GPa and its pressure derivative [B_o'] = 12 (1) as described in the text. The estimated standard deviations of a, c and V/Vo are smaller than the plotted symbols for most of the points, and the solid curves for the lattice parameters a and c are guides to the eye.
