Abstract 

Roughness of the interfaces between layers in a multilayer magnetic
structure causes frustration of the exchange interaction between spins.
Under certain conditions, frustration brings about the formation of domain
walls (DWs) of a new type, whose parameters are determined by the
competition between different exchange interactions rather than between
the exchange and anisotropy energies as is the case with conventional DWs.
Such DWs are much sharper than conventional DWs. The conditions under
which micro- (nano-) domains arise are considered, and magnetic phase
diagrams for ferromagnet nonmagnetic metal ferromagnet and ferromagnet
antiferromagnet nanostructures are discussed.
