Abstract
By field‐annealing barium sodium niobate crystals in the presence of H2O and D2O vapor it is established that protons diffuse into the crystals. As a result of this diffusion, the crystal resistivity is found to increase by a factor of ∼2×103. It is concluded that diffusion of protons into ferroelectric barium sodium niobate and other high‐temperature ferroelectrics is necessary before the crystal dipole moment can be freely reversed by an external electric field.Keywords
