Temperature dependence of the Raman dispersion of Sr2Nb2O7: Influence of an electric field during the synthesis

We report on the preparation and structural characterization of powder samples of the perovskite‐slab layered polycrystalline Sr2Nb2O7 (hereafter named SNO) ferroelectric compound. Comparison is performed on samples grown without (SNO) and with an applied electric field of 3.34 kV/cm (SNOE). The Ram...
