Excitation of magnetic inhomogeneities in three-layer ferromagnetic structure with different parameters of the magnetic anisotropy and exchange

• The generation of magnetic inhomogeneities in the three-layer ferromagnetic.
• The influence of an external field on the parameters of magnetic inhomogeneities.
• Numerical study of the structure and dynamics of magnetic inhomogeneities.

The generation and evolution of magnetic inhomogeneities, emerging in a thin flat layer with the parameters of the magnetic anisotropy and exchange interaction, with the parameters different from other two thick layers of the three-layer ferromagnetic structure, were investigated. The parameters ranges that determine the possibility of their existence were found. The possibility of the external magnetic field influence on the structure and dynamic properties of localized magnetic inhomogeneities was shown.
