Abstract: We study ferroelectricity in thin films of pseudoproper ferroelectrics such as the so-called spiral multiferroics. We find that this type of ferroelectricity stands better against depolarizing fields than conventional one. Its single-domain state can be easily preserved by metallic electrodes even in ultrathin films. In fact, single-domain ferroelectricty can be generated as a metastable state in the absence of electrodes. We also find a regime of small thickness where unscreened films develop unusual multi-domain states whose properties are sensitive to nonelectrostatic boundary conditions.
