## 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
Polycrystalline 0.80Pb[(Mg 2/3 Zn 1/3 ) 1/3 Ta 2/3 ]O 3 -0.20PbTiO 3 (PMZT-PT) having a tetragonal perovskite type structure was prepared by the high temperature solid-state reaction method. Dielectric studies showed the relaxor behaviour with diffuse phase transition. High value of m 48000 was real
