Abstract

Large range ordered La(0.7)Sr(0.3)MnO(3) and SrRuO(3) epitaxial dots were fabricated by pulsed laser deposition using stencil masks and were embedded in ferroelectric PbTiO(3) epitaxial films. PbTiO(3) films grown on top of La(0.7)Sr(0.3)MnO(3) dots form arrays of 180 degrees domains that are switchable and have good ferroelectric properties. PbTiO(3) films made on top of SrRuO(3) 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 degrees ferroelectric domains.
