Vy. Topolov et Av. Turik, ELECTROMECHANICAL CONSTANTS AND THEIR ANISOTROPY IN LINBO3-TYPE CRYSTALS HAVING 180-DEGREES INCLINED DOMAIN-WALLS, Journal of physics. Condensed matter, 10(2), 1998, pp. 451-459
The paper is devoted to the determination of effective electromechanic
al constants d(ij)(p), e(ij)(p), epsilon(kl)(sigma p) and s(fg)(E,p) o
f polydomain LiNbO3 and LiNb0.1 Ta0.9O3 crystals at room temperature.
180 degrees domain structures considered here contain inclined plane w
alls providing a significant anisotropy of piezoelectric constants e(i
j)(p). The effect of such domain structures is established for the fir
st time and discussed.
