Pressure-induced ferroelectric to antiferroelectric phase transition in Pb{sub 0.99}(Zr{sub 0.95}Ti{sub 0.05}){sub 0.08}Nb{sub 0.2}O{sub 3}

Journal Article Avdeev, Maxim ; Jorgensen, James D ; Short, Simine ; ... - Physical Review. B, Condensed Matter and Materials Physics

Zr-rich, Nb-doped lead zirconate titanate ceramic and powder samples with composition near Pb{sub 0.99}(Zr{sub 0.95}Ti{sub 0.05}){sub 0.98}Nb{sub 0.02}O{sub 3} [PZT95/5(2Nb)] have been studied in the range of hydrostatic pressure 0-6.2 kbar and temperature 12-295 K by time-of-flight neutron powder diffraction and dielectric measurements. The combination of the two techniques has led to further insights into the properties and pressure-induced ferroelectric rhombohedral R3c (F{sub R(LT)}) to antiferroelectric orthorhombic Pbam (A{sub O}) phase transition in this material, and the diffraction results have provided a detailed view of the ionic displacements induced by changes in pressure and temperature as well as the displacementsmore »« less
