Abstract

Large range ordered La_0.7Sr_0.3MnO₃ and SrRuO₃ epitaxial dots were fabricated by pulsed laser deposition using stencil masks and were embedded in ferroelectric PbTiO₃ epitaxial films. PbTiO₃ films grown on top of La_0.7Sr _0.3MnO₃ dots form arrays of 180 domains that are switchable and have good ferroelectric properties. PbTiO₃ films made on top of SrRuO₃ dots have a monodomain polarization state. These observations point out the importance of the electronic properties of the bottom electrode in the selection of a preferential polarization state in epitaxial ferroelectric films and propose a route of fabricating large arrays of switchable 180 ferroelectric domains.
