## Abstract The refractive indices of 0.9Pb(Zn~1/3~Nb~2/3~)O~3~‐0.1PbTiO~3~ single crystal at different wavelengths have been measured by the minimum deviation method at room temperature, and their dispersion equations are obtained. The parameters connected to the energy band structure are obtained
High Resolution Electron Microscopy (HREM) images of PMN \(\left(\mathrm{PbMg}_{1 / 3} \mathrm{Nb}_{2 / 3} \mathrm{O}_{3}\right)\) taken along a \(\langle 110\rangle\) axis of the cubic (perovskite) structure show that ordered regions of the \(\{111\}\) type exist which correspond to \(A B_{1 / 2}^{
