Abstract:

Self-organization processes that appear as formation of spiral dynamic domains were studied in iron garnets epitaxial films. Application of statistics methods to analysis of large experimental dataset on spiral dynamic domains allowed establishing a threshold character of spiral dynamic domains spatial and temporal characteristics temperature dependencies. The threshold temperature, at which characteristics of spiral dynamic domains exhibit a sharp change, coincides with the temperature of most intense formation of the domains.
