摘要

The phenomenon of switching of the domain walls generated by frustrations in a two-layer ferromagnet-antiferromagnet nanostructure has been studied theoretically taking into account the energy of the uniaxial anisotropy beyond the exchange approximation. This phenomenon manifests itself in the fact that, as the magnetic field increases, the ferromagnetic layer divided into nanodomains by domain walls perpendicular to the layer plane becomes single-domain, and the antiferromagnetic layer that is uniform in weak fields is divided into 180° domains by the domain walls perpendicular to the layer. The phase diagram of the two-layer nanostructure has been constructed in the variables "the magnetic field-the characteristic distance between atomic step edges at the interface between the layers."
