| Popis: |
A Raman scattering spectroscopy study is reported through all four phases of a (K0.5Na0.5)NbO3 crystal and ((K0.5Na0.5)1-xLix)NbO3 for x=0.02 and 0.03. The transitions among the ferroelectric phases in the Li-free crystal are homogeneous and strongly hysteretic, with no evidence of a mixed-phase region between the rhombohedral and orthorhombic phases. The Raman pattern in the lowest-temperature phase in the Li-doped material differs significantly from that found for x=0 and suggest a structural phase boundary exists at for a Li concentration of less than 2%. |
