Abstract
The effect of fatigue in BaTiO3 monocrystals was studied. Observed were: high degree and rate of aging of some specimens in fields E=3 to 4 kV/cm under the application of a certain type of sequence of pulses; identity of the processes of formation, and of regeneration of fatigue-failed samples; series of changes generated by aging in the mechnism of switching; increase of permittivity and reduction of residual polarization determined from pyroelectric effect in fatigue-failed samples. For the explanation of the fatigue the necessity of taking into consideration the nonhomogeneity of properties of monocrystals across their thickness is assumed.
