Figure 8
(a) Temperature-dependence of the dimensionless correlation parameter φ for the nearest Y—O (circles) and Y—Y bonds (squares and triangles). Solid and dashed lines are guides for the eye. (b) Calculated MSRD factors for Y—O (solid squares) and Y—Y (open circles) plotted versus the interatomic distance R. The solid line is a sum of MSDs for Y and O, the dashed line is a sum of two MSDs of Y. All results are obtained from the MD simulations at 300 K using the force-field model (Model 1) from Bose et al. (2011). |
