Figure 1
Temperature evolution of the Laue patterns: (a) corresponds to the orthorhombic phase collected at 138 K, (b)–(i) correspond to an enlarged area, highlighted in (a) and (j) with a white rectangle. The (b)–(i) patterns were collected at approximately 135.5, 127.5, 122.5, 114, 105, 94, 81 and 77 K, respectively. The (j) pattern, collected at 65 K, corresponds to the monoclinic phase. The splitting of the nuclear reflection into two twin domains is caused by the breaking of symmetry.
