Abstract :
It is known that longitudinal and transversal piezoelectric coefficients of (111)c, oriented poled tetragonal crystal plate depend on its domain structure. Expected strong variation of these coefficients for different domain patterns in poled crystals was experimentally confirmed on the example of BaTiO3 single crystal. The correlation between a piezoelectric coefficient d31 and the domain pattern observed with polarizing microscope is shown.
