51 573. The thickness dependence of the permittivity of barium titanate single crystals. Czechoslovakia. A thickness dependence of the permittivity of c-domain barium titanate single crystals was found. The experimental results were explained by means of a model of a dielectric with surface layers. The thickness of the layer and the permittivity of the surface layer and bulk of the crystal were (Authors) determined. P. Coufov& and H. Arend, 308-312. 52.
