Castro* Departamento de Física Aplicada, Universidad de Santiago de Compostela, E-15706 Santiago de Compostela, Spain S. T. Chui Bartol Research Institute, University of Delaware, Newark, Delaware 19716 V. N. Ryzhov Institute for High Pressure Physics, Russian Academy of Sciences, 142 092 Troitsk, Moscow region, Russia Received 16 March 1999; revised 17 May 1999 We show that many of the domain patterns in ultrathin films with in-plane magnetizations from experiments and from computer simulations can be well approximated as local extrema of the exchange and anisotropy energies with appropriate boundary conditions. These solutions can be obtained analytically from the many soliton solution of the imaginary time sine-Gordon equation. Different types of these solutions are represented and their physical meaning is discussed. ©1999 The American Physical Society URL: http://link.aps.org/abstract/PRB/v60/p10271 DOI: 10.1103/PhysRevB.60.10271 PACS: 75.70.Kw ------------------------------------------------------------------------ * Electronic address: facastro@usc.es ------------------------------------------------------------------------ Add to article collection View PDF (233 kB) [ Previous article | Next article | Issue 14 contents ] ------------------------------------------------------------------------ References (Reference links marked with dot may require a separate subscription.) 1.
