Abstract

We report the broadband light-scattering spectroscopy of a single crystal of a prototypical relaxor ferroelectric, Pb（Mg_1/3Nb_2/3）O₃. A self-similar, “power-law central peak” has been observed, indicating the presence of a fractal in the crystal. A strong correspondence exists between the temperature dependence of the power exponent, and that of the reported behaviors of “polar nanoregions”, which consist of the fractal percolation cluster in the crystalline matrix of the material.
