Abstract
We propose a mechanism of stochastic resonance induced by spatial noise (electric random fields) in ferroelectrics. The calculations demonstrate the characteristic of the stochastic resonance: certain random field can increase the susceptibility, the phonon occupancy, and the overcooled temperature. This mechanics of stochastic resonance may be general in other disordered systems.
