One-dimensional dynamics of domain walls in two-layer ferromagnet structure with different parameters of magnetic anisotropy and exchange

► Simulating the non-linear dynamics of domain walls in the two-layer ferromagnet. ► The minimum speed necessary for a domain wall passing through the defect region. ► Pinning of a single domain wall in the defect region. ► The translational and pulsation modes of the domain wall have been calculated.
