Modeling of nonlinear processes on magnetostatic waves in coupled ferromagnetic structures

Autors:

Abstract: 

System of nonlinear equations is obtained for the direct—volume—magnetostatic waves envelope solitons propagation in the coupling two—films ferromagnetic structure. Some features of soliton formation arising are considered in the framework of the numerical modeling at various structure parameters. The influence of the main structure parameters, pulse frequency and the dissipation on the process of the magnetostatic waves envelope soliton formation is examined.
