Abstract

The motion of sparse charge carriers in highly insulating materials has so far only been partly accessible to common techniques such as drift current or Hall measurements due to the high resistivities encountered. In the case of a ferroelectric–ferroelastic the reordering of point defects under applied electric and magnetic fields is demonstrated utilizing the ferroelastic coupling. The method is independent of surface conductivity contributions and nonpercolating conductivity paths in the bulk. For highly compensated soft doped lead zirconate titanate, electrons dominate charge transport in virgin and holes in fatigued samples.
