Recently, several proton-conducting oxides, including In³⁺-doped BaZrO₃, have been found to have significant electrostrictive effects after hydration. In this study, epitaxial films of BaSn_0.6In_0.4O_2.8 were fabricated, and the lattice distortion due to hydration and electrostriction properties were measured. The results of 2θ/ω scans of the hydrated samples while a static electric field was applied suggest that the lattice constant decreased regardless of the direction of the electric field, indicating the possibility of a negative electrostriction effect.
