Abstract
The transition from a ferroelectric to a relaxor is described. Asymmetric double-well potentials for fluctuating charges, dipoles or polar nanoregions and a feedback between these double wells are employed. Tuning the intrinsic asymmetry it is possible to describe either a ferroelectric state or a relaxor behavior. While in ferroelectrics with an ordered crystal lattice the intrinsic asymmetry is small, disorder in the amorphous state can result in double wells with higher asymmetry causing a relaxor response.
