Comparative Acoustic and Contact Studies of Elasticity of Ferroelectric Li_xNa_{1 - x}Ta_0.1Nb_0.9O₃ Solid Solutions at Nanometer Spatial Resolution

Abstract

Comparative acoustic and contact studies of elastic properties of the Li _x Na _1−x Ta _0.1 Nb _0.9 O ₃ (x = 0.015–0.135) ferroelectric solid solution ceramics are reported. A good agreement is obtained between the values of elastic modules determined by acoustic and contact methods at nano-scale spatial resolution.
