Abstract

We report Raman spectroscopy in all four phases of a (K(0.5+delta)Na(0.5-delta))NbO(3) (delta similar to 0.03) crystal and ((K(0.5+delta)Na(0.5-delta))(1-x)Li(x))NbO(3) for x=0.02 and 0.03. The phase transitions in the Li-free crystal are homogeneous and hysteretic, with no mixed-phase region between the rhombohedral and orthorhombic phases. Raman spectra in the lowest-temperature phase in the Li-doped material differ significantly from those at x=0 and suggest a structural phase boundary at a Li concentration of less than 2%.
