Abstract
It is shown that the motion of a domain wall in the improper ferroelectric- ferroelastic gadolinium molybdate Gd-2(MoO4)(3) demonstrates a self-organiz ed critical behavior under polarization reversal. Barkhausen pulses are mea sured experimentally during the jumpwise motion of a single plane domain wa ll in monocrystalline plates with artificial pinning centers of the "field inhomogeneity" type.
