Figure 2
Synchrotron XRD patterns collected at room temperature (∼293 K) of (a) Ba2La2NiW2O12 and (b) Sr2La2NiW2O12. The black symbols, red curve and blue curve correspond to the observed data, calculated pattern and difference curve, respectively. Black vertical bars (top) refer to Bragg angles of the main phase while the secondary ones below refer to (a) BaWO4 and La2O3 and (b) SrWO4. |
