Abstract

Domain switching has been observed in 0.9PZN - 0.1PT single crystals under the influence of electric field. The crystal being near the morphotropic phase boundary contains two phases - rhombohedral and tetragonbal. The electric field was applied along two principal directions [001] and [111]. Their formation as the temperature is reduced with the electric field is discussed here. For electric field along [001]. It was found that a single domain could be induced in tetragonal phase. When the electric field was applied along [111], the formation of domains as temperature is reduced are shown to be remarkably similar to those formed when the temperature is fixed and the concentration of PT varied. This type of domain hierarchy may be a contributing factor for the high k (electromechanical factor) observed in these crystals.
