Pressure-induced crossover from long-to-short-range order in [Pb(Zn{sub 1/3})Nb{sub 2/3}O{sub 3}]{sub 0.905}(PbTiO{sub 3}){sub 0.095} single crystal
A pressure-induced crossover from normal Ferroelectric-to-Relaxer behavior has been observed in single crystal [Pb(Zn{sub 1/3}Nb{sub 2/3})O{sub 3}]{sub 0.905}(PbTiO{sub 3}){sub 0.0095}, or PZN - 9.5% PT. Analogy with similar observations for other perovskites indicates that this crossover is a general feature of compositionally-disordered soft mode ferroelectrics. The Pressure-Temperature phase diagram has been also determined.
