- 論文の詳細を見る
Polarization reversal in BaTi03 is discussed taking account of neutralizingelectrons or tons upon the crystal surface. The neutralizing charges spread on thesurface of one c-domain from another one separated by the 180'-type domainwall, and build up there a kind of wall of moderate or large (especially in liquidelectrode) thickness, which plays an important role in the side-wise motion of thewall during the reversal process. Since the property of electrodes has a greatinfluence upon the creation of the wall, the behaviour of the side-wise motion hasthe great difference among metal, semiconductor and liquid. The rapid side-wisemotion in liquid electode can be attributed to the extensive thickness of the wallin this case. The origin of the central peak in neutron diffraction is discussed fromthe scope of the displacement of front walls and also the side-wise motion of thiswalls.
