Anomalies in the Raman scattering spectra of piezoelectric BaZnF4 crystals
Publikation: Bidrag til tidsskrift › Tidsskriftartikel › Forskning › fagfællebedømt
A Raman scattering investigation of the piezoelectric compound BaZnF4 has been performed in a wide temperature range. An accurate study of the characteristics, i.e. peak shifts, integrated intensities and half-widths, reveals anomalous changes in several spectral lines. The results are discussed on the basis of a breakdown of the q=0 selection rules due to either a phase transition or structural disorder.
