Resumo
The pyroelectric properties and state of polarization of calcium barium niobate single crystals CaxBa1–xNb2O6 (CBN) with x = 0.28, 0.30, and 0.32 are studied. It is shown that in contrast to CBN30 and CBN32 crystals, the effect of the alternating electric fields higher than the coercive field changes the state of polarization in the surface layer of the CBN28 crystal. At the same time, thermal cycling to temperatures higher than the Curie point leads to the formation of a system of antiparallel domains in CBN30 and CBN32 crystals, and to complete depolarization of CBN28 crystals.
