摘要

The multidomain structure evolution in Pb(Zr,Ti)O_3 ultrathin films subject to an electric field applied along the pseudocubic [111] direction is investigated via the use of an effective Hamiltonian. Varying the magnitude of this electric field (that possesses both in-plane and out-of-plane components) leads to the formation of five different states, whose microstructures and properties are revealed here. Such variation also makes the polarization changing not only in magnitude but also in direction. The field-induced correlation between the polar distortions and the oxygen octahedral tilting is also discussed as an important factor affecting the polarization.
