Figure 2
(a) Pressure dependence of the relative lattice parameters, relative c/a axial ratios and relative unit-cell volumes. The solid line is a Murnaghan equation of state fit to the compressibility data. (b) Relative lattice parameter and c/a ratio of BaV6O11 as a function of unit-cell volume. Filled symbols represent datapoints measured as a function of temperature (Friese & Kanke, 2006), open symbols are datapoints measured as a function of pressure. |
