dc.description.abstractWe studied the soft phonon Raman spectra in samples of K1-xLixTa1-yNbyO3, with x = 0.0015, y = 0.046 and x = 0.0024, y = 0.01 mol% in order to explore the complex structural effects arising in KTaO3 matrix, weakly doped by Li (x < 0.01) and simultaneously moderately doped by Nb (0.01 <= y <= 0.05). The results provide new evidence that the character of the phase transitions in KTaO3 moderately doped with Nb, can be markedly modified by the addition of small amounts of Li. In particular K0.9976Li0.0015Ta0.954Nb0.046O3 exhibits a complex scenario of structural transformations, that differs from the known behaviour in KTN close to the multicritical point.
