摘要：

The dielectric permittivity of BaTiO3 polydomain crystals with 90° domain walls is investigated over a wide frequency range. It is shown that reversible 90° reorientations of domains occuring in these crystals produce a great contribution to the dielectric permittivity, electromechanical coupling factors, piezoelectric constants and elastic compliance coefficients. Two regions of dispersion of permittivity which are related with piezoelectric oscillations of the whole crystal and individual domains are found. © 1978, Taylor & Francis Group, LLC.
