Spontaneous polarization (Ps) in epitaxial film of 2% Dy3+-substituted tetragonal Pb(Zr0.40Ti0.60)O3 [Dy–PZT] was compared with that of nonsubstituted Pb(Zr0.40Ti0.60)O3 [PZT] to investigate intrinsic contribution of the Dy3+ substituion to the Ps improvement. Epitaxial thin films of PZT and Dy–PZT with (111) orientations were grown on (111)cSrRuO3//(111)Pt//(100)YSZ//(100)Si substrates by chemical solution deposition. The saturated polarization values of PZT and Dy-PZT films with (111) orientation were 41 and 48  µC/cm2, respectively. The estimated Ps values of PZT and Dy–PZT films from the saturation polarization values were 71 and 84  µC/cm2, respectively. The Ps value of this PZT was in good agreement with previous reports. The increase in Ps of the epitaxial Dy3+-substituted PZT film is attributed to the enhancement of the crystal anisotropy, i.e., tetragonality, of the tetragonal PZT lattice. This shows that the enhancement of the ferroelectricity of the tetragonal PZT films can be achieved by ion substitution, just as it can in Bi4Ti3O12-based film.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Institute of Physics"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1063/1.2125123","subitem_relation_type_select":"DOI"}}]},"item_2_rights_14":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright 2005 American Institute of Physics.
