Zusammenfassung:The ferroelectric domain structures in the < 110 > oriented K3Li2-xNb5+xO15+2x (KLN) single-crystal fibers have a bidomain configuration from the results of the piezoelectric, and scanning nonlinear dielectric microscopy measurements. The directions of spontaneous polarization faced each other across the domain boundary, as opposed to the case in LiNbO3 fibers. A new mechanism based on the stress during the growth is proposed to explain the domain structures of the KLN fibers. 11 refs.
