Abstract :
0.93(PbZn13/Nb23/)-0.07PbTiO3 single crystals with and without MnO2 addition have been synthesised by the classical flux method. The structural transition temperatures have been investigated by X-ray diffraction and dielectric measurements. Mn doping was found to shift down the structural transition temperatures. Electromechanical and dielectric properties of [111] oriented rhombohedral single domain crystals have shown an intrinsic contribution of Mn doping on the dielectric permittivity (ε) and on the piezoelectric coefficient (d31).
