Anomalous small-angle scattering of light in ferroelectrics with diffuse phase transition
Kamzina L. S. , Korzhenevskii A. L.
An anomalous small-angle scattering of light has been observed in crystals of PbSc, /2Ta, /203 (PST), which undergo diffuse phase transitions. The experimental data are consistent with the assertion that a diffuse phase transition in disordered PST crystals is accompanied by a percolation phase transition.
