Abstract:Crystal structure parameters of the mixed cobaltite–chromite SmCo0.5Cr0.5O3 in the temperature range of 298–1173 K were derived from in situ high‐resolution X‐ray synchrotron powder diffraction data. Similar to the parent SmCoO3 compound, SmCo0.5Cr0.5O3 reveals anomalous thermal expansion reflected in abnormal temperature dependence of the unit cell dimensions and the selected interatomic distances and angles. These anomalies are associated with temperature induced changes of spin state of Co3+ ions and couple… Show more
