Аннотация: The λ-shaped line width broadening anomalies of octahedron group vibrations in Rb2KMoO3F3 disordered crystal have been revealed in the wide temperature range by Raman technique. The line width of Mo-O and Mo-F vibrations in this crystal is connected with the lattice disorder. The dependence of ordering degree passing the phase transition point history has been discovered. Wide temperature-line width area is found below structural phase transition where different lattice disorder can be obtained at a given temperature by varying the rate of sample cooling. The current study demonstrates the ability of a dynamic temperature regime to control ordering processes in crystals. © 2014 American Chemical Society.
