Jpn J Appl Phys, 50(9) 09ND11-09ND11-4, Sep 25, 2011Films of solid solution in KNbO3--NaNbO3(KNN) were deposited at 240 °C on (100)\text{cSrRuO3$\varparallel$(100)SrTiO3substrates by the hydrothermal method. (KxNa1-x)NbO3films with $x = 0{\mbox{-- } }1.0$ were synthesized by changing the fraction of KOH in a solution of KOH and NaOH. The $x$ in (KxNa1-x)NbO3continuously changed with the volume fraction of KOH, while the deposition amount strongly depended on $x$. Epitaxial films with {100} orientation were obtained in the entire composition range and their out-of-plane lattice spacing changed with $x$. All the films showed ferroelectricity and their remanent polarization became larger than what above $x = 0.58$.

Preprints of Annual Meeting of The Ceramic Society of Japan<br>Preprints of Fall Meeting of The Ceramic Society of Japan, 2010 2P015-2P015, 2010We fabricated novel candidate, Bi(Zn1/2Ti1/2)O3-BiFeO3for ferro/piezoelectric materials. However, Tetragonal distortion of 1.22 is too higher for ferroelectric switching than that of PbTiO3 and need to decrease. In the present study, tetragonal distortion of Bi(Zn1/2Ti1/2)O3-BiFeO3 was reduced by Bi(Mg1/2Ti1/2)O3 substitution. In addition, new peak which had non tetragonal phase was appeared at x = 0.30 composition in xBi(Mg1/2Ti1/2)O3-(1-x)Bi(Zn1/2Ti1/2)O3-BiFeO3 thin films.
