“…The properties of giant piezoelectric, electrostriction, and diffusion peak in its dielectric versus temperature characteristic have been extensively studied based on the application of actuators, transducers, and capacitors (Levoska et al, 2000). PbMg 1/3 Nb 2/3 O 3 -PbTiO 3 (PMN-PT) exhibits excellent relaxor properties and has likewise been extensively studied (Zhao et al, 1995;Zhang and Zhao, 1997). In bulk material, PMN-PT with compositions having less than 33 mol% of PT show relaxor behavior, associated with a diffuse peak in its dielectric versus temperature characteristic.…”
