Oxygen Content and Thermodynamic Stability of YBaCo₂O_6−δ Double Perovskite

Figure 2

X-ray diffraction pattern and its matching refinement plot of YBaCo₂O_6−δ: observed X-ray diffraction intensity (points) and calculated curve (line). The bottom curve is the difference of patterns, y_obs − y_cal, and the small bars indicate the angular positions of the allowed Bragg reflections.
