Evolution and parameters of dynamic domain structures of the “leаding center” type

A detailed study of the behavior of ordered, stable dynamic domain structures (DDS) of the "leading center" (CC) type, determination of the quantitative characteristics of these DDSs were carried out [1, 5] on several samples of garnet-ferrite films, for which, according to dynamic domain phase diagrams (PD) , there were large amplitude-frequency regions (H0-f) of the existence of this type of DDS. In this work, the dependence of the geometric dimensions of the BVTs (the number of rings and the outer diameter) on the conditions of energy pumping is investigated. The dependence of the number of annular domains (CD) N, “black” and “white”, was also established with a change in the amplitude H0 and fixed frequencies f.
