Precessing ball solitons as dissipative structures during a phase transition in a ferromagnet

By V. Nietz

Abstract

Precessing ball solitons (PBS) in a ferromagnet during the first order phase transition induced by a magnetic field directed along the axis of anisotropy, while the action of the periodic field perpendicular to the main magnetic field, have been analyzed. Under this condition, the characteristics of arising equilibrium PBS's are uniquely determined by the frequency of the periodic field, but the solitons with other frequencies are impossible. It is shown that the equilibrium PBS's are essentially the "dissipative structures" that can arise in a metastable state.Comment: 8 pages, 11 figure
