Light scattering and singularities of the crystal structure of quartz at its phase-transition point
Shustin O.A., Chernevich T.G., Ivanov S.A., Yakovlev L.A.
Results are described of an investigation of a new phenomenon—the formation of a macroscopic phase structure at the α-β phase transition point of quartz crystals. The results are of importance for the elucidation of the mechanism of phase transitions in crystals.
