Abstract

Selected results of original numeric simulations of non-linear magnetostatic spin waves and microwave-frequency magnetic chaos in ferrite films are expounded, as third part of the work whose first two parts are recent arXive preprints 1204.0200 and 1204.2423 . Especially we consider crucial role of parametric processes in creating the chaos and simultaneously obstacles to its synchronization, and examine some possibilities of good enough synchronization (to an extent allowing its use for direct secure communication in microwave band).
