Fractal nature of large-scale nonuniform states in ferroelectrics with a diffuse phase transition
The angular distribution of the anomalous component of the scattered-light intensity, 1(0), in disordered òøâÓ^ôÁÝïÚ crystals has been measured. A power-law distribution Ι(θ) α Q~a, where or—3.2, was observed as the intensity was varied over four orders of magnitude. The physical nature of the optical irregularities, whose length scales are broadly distributed, is discussed in terms of a fractal model. © 1995 American Institute of Physics.
