Abstract
Raman scattering and infrared absorption studies of ferroelectric SbNbO4, antiferroelectric BiNbO4, and the solid solution (Sb1-xBix)NbO4 for 0 < x < 1 in the range 20-1200 cm−1 are reported. These are the first vibrational spectroscopic investigations in these stibiotantalite-type systems. Symmetry assignments are proposed for the internal modes. Such an assignment is shown to lead to a consistent set of values for the local force constants calculated under the general quadratic valence force field. The nature of the variations of lattice and internal frequencies with changes in A3+-ion concentration is qualitatively discussed with particular reference to the ferroelectric soft mode.
