Figure 3
Site occupancy factors of Ti at the different Ti subdomains in Ca5Nb4TiO17 (n = 5, filled triangles and the solid line) and Ca6(Nb,Ti)6O20 (n = 6, open triangles and dotted line). The curves are obtained by fits of pseudo-Voigt functions centred at t = 0 to the data points. For the sake of clarity the subdomains as defined in Fig. 2 are also indicated at the bottom (n = 5) and the top (n = 6) of the graph. |
