Figure 2
Lattice parameters of Pmmn-NiSi as a function of unit-cell volume from this study (black circles) and the ab initio simulations of Wood et al. (2013; open circles with dashed lines). The solid lines are polynomial fits of second order to the experimental data collected in this study. Note the break in the y axis at y ≃ 3.4. The kink in the ab initio lattice parameters can be seen much more clearly in Fig. 4(a) of Wood et al. (2013). |
