On the 180°-type Domain Wall of BaTiO3 Crystal

摘要: The energy of the 180°-type domain wall BaTiO 3 crystal is obtained as 1.4 erg/cm 2 considering dipole interaction and other interatomic Born type. term has been approximately from difference ferroelectric antiferroelectric (stripes type) configurations. found to be quite thin, that is, change polarization at boundary abrupt, in contrast with ferromagnetic walls. structure 180° domains their reversing process are also discussed.
