Abstract
Low‐frequency dielectric constantmeasurements vs temperature and electric field indicate that the ferroelectric transition in Pb3MgNb2O9 is second order. The quadratic electro‐optic coefficients in Pb3MgNb2O9 are approximately an order of magnitude smaller than those of KTN (KTa.65Nb.35O3); however, the electronic conduction effects and compositional inhomogeneity problems encountered in KTN are absent in Pb3MgNb2O9, thus making it a practically useful electro‐optic material.Keywords
