Hydrostatic Parameters and Domain Effects in Novel 2-2 Composites Based on PZN-0.12PT Single Crystals

Figure 1

Schematic of the 2-2 parallel-connected SC/polymer composite. (𝑋₁𝑋₂𝑋₃) is the rectangular co-ordinate system of the composite sample α and β are angles of rotation of the spontaneous polarisation vector 𝐏^𝐬(𝟏)‖𝑂𝑋^3 of the single-domain SC layer around the 𝑂𝑋₁ axis (inset 1) or around the 𝑂𝑋₂ axis (inset 2). In inset 3 the 90° domain structure in the SC layer is schematically shown, where 𝑚_𝑑 and 1−𝑚_𝑑 are volume fractions of the 90° domains in the SC layer, and their spontaneous polarisation vectors are shown with arrows.
