An influence of a planar electric field on material coefficients of a barium titanate film has been studied. Electric-field dependences of dielectric constants, elastic and piezoelectric moduli were built for the (001)-oriented film on a cubic substrate with a misfit strain value equal to . It was revealed that an electromechanical coupling coefficient, k11, has a maximum at some value of the electric field, which depends on the clamping stress. The misfit strain dependence of the maximum value of the k11 coefficient was studied at strains below (c-phase).
