    It is shown that the intercell dipole-dipole (polarization) interaction lowers the frequencies of the polar transverse-optical (TO) lattice vibrational modes (to a greater extent, the larger the corresponding dipole oscillator strengths) and can be a cause of ferroelectric instability in...

    Crystalline potassium dideuterophosphate subjected to a slowly varying or a dc electric field has been found to exhibit polarization features which indicate the presence of a structural disorder characteristic of inhomogeneous systems. Continuous distribution spectra of the relaxation time are...

    The abnormal polarization offset observed in case of graded ferroelectric structures is explained assuming the presence of a nonreversible part of polarization due to the imposed polarization gradient. It is shown that an upper limit for the offset should exist, fixed by the remnant polarization...
