We have investigated the electronic ferroelectric material YFeO
by means of electron transmission microscopy. The measurement at room temperature showed the charge-ordered structure of Fe ions in the a-b plane, which is the origin of ferroelectricity. An enlargement of unit cell along the c-axis was also observed. These phenomena were not observed at high temperatures around 600 K. That is, the charge ordering in the a-b plane appeared below about 500 K, whreas the enlargement of unit cell along the c-axis was found at room temperature. Below 100 K, an additional enlargement of unit cell along [119] was observed. This behavior is characteristic of YFeO. These results are discussed in connection with the dielectric properties.
