RELAXATION PROCESSES AND DIAGNOSTICS OF PHASE STATES IN CONDENSED MATTER

This paper sums up studies on low-frequency relaxation processes that involve several macroheterogeneities and critical points, the existenc e of thermodynamically stable microheterogeneities, associated critica l points of micelle formation, structural phase transitions, and phase transitions traceable to an anomalous increase in the mobility of ion s in superionic crystals. A detailed description is given of precision low-frequency techniques, their evolution, and capabilities as tools of research on a wide range of objects, including multicomponent segre gating and nonsegregating liquid solutions, micelle-forming solutions, and superionic solid conductors.
