Figure 7
PDF curves of (a) PLZT15 at room temperature, (b) PLZT12 at room temperature, (c) PLZT11 at room temperature and (d) PLZT11 at 673 K. Experimental: blue circles; cubic and/or tetragonal model: red line. Measurements at room temperature were modeled with a non-centrosymmetric tetragonal P4mm cell, and the PLZT11 at 673 K was fitted with a cubic structure. We include the reduced and the Rw values. |
