We present a phenomenological model of periodic ferroelectric‐superconductor (FE‐S) heterostructures containing two alternating ferroelectric and superconducting layers. The interaction at the FE‐S contacts is described as a coupling of the local carrier density of the superconductor with the spontaneous ferroelectric polarization near the FE‐S interface. For the stronger coupling, we find a stable symmetric domain‐type phase exhibiting the ferroelectric domain structure. With a further increase of the coupling energy, we obtain the complete suppression of the superconducting state in the S‐film. The behavior of the system is discussed for different thicknesses of the S‐films.
