Figure 2
Observed (dots), calculated (continuous line) and difference (bottom line) profiles of 110, 111 and 200 pseudocubic reflections of Pb(Zr0.525Ti0.475)O3 using (a) coexistence of rhombohedral and tetragonal and (b) pure monoclinic (Cm) structural models. The vertical tick marks above the difference profiles give the positions of the Bragg reflections (after Singh et al., 2007a). |
