We report here the growth of Pt electrodes presenting at the same time an ultraflat surface (rms=0.3 nm) and a perfect (111) monocrystalline orientation. These electrodes were grown by pulsed laser deposition on yttrium-stabilized zirconia (111), using a few nanometers thick titanium adhesion layer. Such high crystalline quality electrodes allow the growth of subsequent layers with a very reduced number of variants. They therefore open perspectives for the anisotropic characterization of multiferroic or magnetoelectric materials. The optimized growth of the magnetoelectric GaFeO3 on such a Pt(111) electrode is shown as an example.
