Abstract The domain reversal characteristics of near-stoichiometric LiNbO3([Li]/[Li+Nb]=0.496) single crystals, which are grown by the Czochralski method with K2O flux, are investigated. The switch field for 180o ferroelectric domain reversal in the near-stoichiometric LiNbO3 crystal is 8.0±0.5kV/mm, which is only one third of the switching field required for the congruent LiNbO3 crystals. We have successfully achieved 180o domain reversal in near-stoichiometric LiNbO3 samples of 1.0 mm thickness.
