Role of the Mn-doping on the structural and electromechanical properties of 0.93(PbZn/sub 1/3/Nb/sub 2/3/)-0.07PbTiO/sub 3/ single crystals

Role of the Mn-doping on the structural and electromechanical properties of 0.93(PbZn/sub 1/3/Nb/sub 2/3/)-0.07PbTiO/sub 3/ single crystals

0.93(PbZn/sub 1/3/Nb/sub 2/3/)-0.07PbTiO/sub 3/ single crystals with and without MnO/sub 2/ 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 t...

Beschreibung
Zusammenfassung:0.93(PbZn/sub 1/3/Nb/sub 2/3/)-0.07PbTiO/sub 3/ single crystals with and without MnO/sub 2/ 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 (/spl epsi/) and on the piezoelectric coefficient (d/sub 31/).
