Abstract

As far as it is known, the domain structure of the ferroelectrics was not investigated by use of electron optics until now. There is only one publication on the matter concerned here treating, however, the investigation of the domain structure of the ceramic barium titanate (1). The method of investigating the ferroelectric domain structure almost exclusively used at present, was that of polarization microscopy (2). But the small effective magnifications, which could be obtained in this way, did not allow the investigation of domain structures in detail. A more accurate knowledge of these structures might allow a better understanding of some properties of the ferroelectrics not quite clear at present, as for example the high value of the dielectric susceptibility in the saturation region of the barium titanate polarization curve. That is why an electron optical investigation of the ferroelectrics domain structure at high efficient magnifications is important for clarifying some processes taking place in ferroelectrics as well as for better explaining the proper nature of ferroelectricity itself.
