(a) Synchrotron and (b) conventional X-ray powder diffraction profiles of the 004, 020 and 200 reflection peaks of La0.68(Ti0.95,Al0.05)O3, measured at ∼463 K. The lattice spacing (d value in the horizontal axis) was calculated from 2θ with Bragg's equation, λ = 2dsinθ. The values λ = 1.54056 and λ = 1.37852 (6) Å were used for the conventional and synchrotron data, respectively. |
