the structure at various temperatures both below and above the transition temperature 980 K. As the temperature increases‚ the cell parameters and volume increase (Fig. 3 and 4)‚ the tilt angles δ decrease (Fig. 6)‚ and the Fe—O distances decrease (Table 4). The decrease in Fe—O distances is caused by the increasing disorder at high temperature arising from excited low-energy‚ high-amplitude vibrations. The changes stated can also be observed from the ATOMS drawings below. Thermal expansion in the
