Fig. 6. Selected X-ray diffraction patterns of Sr 2 CoFeO 6 at room temperature for various pressures from 2.2 GPa to 31.0 GPa. Some impurity unreacted oxides peaks are marked by asterisks. The wavelength #cod#x03BB; is 0.6199 #cod#x00C5;. In the whole pressure range, the crystal structure of Sr 2 CoFeO 6 remains cubic.
