Fig. 3: Rietveld patterns of Ba7Nb3.9Mo1.1O20.05 at 800 °C.

Rietveld patterns of neutron-diffraction data taken with the (a) backscattering bank (d = 1.1−3.4 Å) and (b) 90o bank (d = 1.6−5.1 Å) of the SuperHRPD diffractometer in vacuum at 800 °C. The observed and calculated intensities and difference plots are shown by red marks, blue and black solid lines, respectively. Black tick marks stand for calculated Bragg peak positions.
