    "abstract": "A stochastical description is applied in order to understand how\nferroelectric structures can be formed. The predictions are compared with\nexperimental data of the so-called electrical fixing: Domains are patterned in\nphotorefractive lithium niobate crystals by the combination of light-induced\nspace-charge fields with externally applied electrical fields. In terms of our\nstochastical model the probability for domain nucleation is modulated according\nto the sum of external and internal fields. The model describes the shape of\nthe domain pattern as well as the effective degree of modulation.",
