N. Bogdanov and U. K. Rößler Leibniz-Institut für Festkörperforschung und Werkstoffforschung Dresden, Postfach 270116, D-01171 Dresden, Germany (Received 8 May 2003; published 16 July 2003) Phenomenological equations for antiferromagnetic structures in a thin antiferromagnetic layer are derived and investigated in a broad range of magnetic fields and layer thicknesses. Corresponding phase diagrams magnetic field vs layer thickness are presented. Depending on thickness and values of the intrinsic and surface-induced interactions, the spin-flop transition occurs either as first-order transition (similar as in bulk materials) or continuously via twisted structures that are inhomogeneous across the layer thickness. The antiferromagnetic twisted phases have the same physical nature and display similar properties as spatially modulated phases observed in confined liquid crystals (Freedericksz effect) or in thin ferromagnetic films and multilayers. ©2003 The American Physical Society URL: http://link.aps.org/abstract/PRB/v68/e012407 doi: 10.1103/PhysRevB.68.012407 PACS: 75.50.Ee, 75.10.-b, 75.30.Kz, 75.70.-i Additional Information ------------------------------------------------------------------------ Full Text: [ PDF (62 kB) GZipped PS Order Document ] ------------------------------------------------------------------------ References Citation links [e.g., Phys.
