摘要: The authors report the structural and ferroelectric properties of Pb(Zr0.52Ti0.48)O3 (PZT) epitaxial thin films grown on (001), (110), (111) SrRuO3∕SrTiO3 substrates by pulsed laser deposition. A monoclinic C (Mc) phase has been found for (101) films, whereas (001) ones were tetragonal (T) rhombohedral (R), respectively. find that polarization Mc is higher than in either T or R ones. These results are consistent with predictions (i) diagrams (ii) enhanced morphotropic boundary PZT related to a low symmetry phase.
