Algebraic value of the electrooptic coefficients and nature of charge carriers in batio3single crystals

1989

Abstract Some monodomain pure and Fe doped barium titanate monocrystals are studied. The algebraic values of the electrooptic coefficients r 13 and r 33 are evaluated using an interferometric method. Then, from energy transfer results it is possible to conclude that majority carriers are positive charges in all the samples.

A new method for the study of antiparallel ferroelectric domains

1992

Abstract Beam-coupling topography is a non-destructive holographic technique for spatially resolved recording of hysteresis loops and for imaging of domains. Its basic principle is interference of rays diffracted from a holographic grating with collinear, transmitted ones. Full domain contrast and noise suppression is achieved by appropriate control of intensity and phase of the interfering beams. The method is applied to antiparallel a-domains in (Sr0.61Ba0.39)Nb2O6:Ce.
