Electrostriction has been studied in 100-200 run thick films of a ferroelectric copolymer P(VDF 70%-TrFE 30%) using applied voltages as low as 10-30 V. The films have been prepared by a Langmuir-Blodgett technique that allows one a layer-by-layer variation of their thickness. To detect a small field-induced deformation (down to 0.001 nm), a spectral Fabry-Perot interferometry in combination with a lock-in technique has been used. As a result, a field dependence of the apparent Young modulus attending polarization switching has been found and discussed.
