Shear piezoelectric properties d₂₄ and d₁₅ of the 0.58PMN-0.42PT crystal and the KNNLT crystal with 4 mm symmetry

Abstract

The 3D space distributions of d₂₄ and d₁₅ of the 0.58PMN-0.42PT crystal and the KNNLT crystal were calculated by the method of the coordinate system rotation. For the 0.58PMN-0.42PT crystal, the values of d₂₄ were larger than those of d₁₅ except the directions of the three coordinate axes. The maximum value of d₂₄ was 250.4pC/N when θ was 48 ̊ 36′, while the maximum value of d₁₅ was 131pC/N in the Z-axis direction. For the KNNLT crystal, the values of d₁₅ were larger than those of d₂₄ except the directions of the three coordinate axes.
