We report the domain structure and ferroelectric properties of a 32 nm-thick Bi0.9Sm0.1FeO3film epitaxially grown on a LaAlO3 (LAO) substrate. This film exhibits a monoclinic Mc phase, with its monoclinic distortion and anisotropy of in-plane (IP) lattice parameters being both smaller than those of...
