Abstract

We report a temperature-dependent Raman scattering investigation of the multiferroic material bismuth ferrite ${\mathrm{BiFeO}}_{3}$ (BFO). The observed loss of the Raman spectrum at the ferroelectric Curie temperature ${T}_{C}$ should be in agreement with a cubic $Pm\overline{3}m$ structure of the ...
