Both, the exchange length of the stray field ls and the magnetocrystalline exchange length lk, are material-dependent quantities that usually lie in the nanometer range. This emphasizes the theoretical challenges associated with the mesoscopic nature of micromagnetism: the magnetic structures are much larger than the atomic lattice constant, but at the same time much smaller than the sample size. In computer simulations, the smallest exchange length serves as an estimate for the largest cell size admissible to prevent appreciable discretization errors. This general rule is not valid in special situations where the magnetization becomes particularly inhomogeneous. When such strongly inhomogeneous structures develop, micromagnetic simulations inevitably contain systematic and numerical errors. It is suggested to combine micromagnetic theory with a Heisenberg model to resolve such problems. We analyze cases where strongly inhomogeneous structures pose limits to standard micromagnetic simulations, arising from fundamental aspects as well as from numerical drawbacks. 000201875 536__ $$0G:(DE-HGF)POF2-422$$a422 - Spin-based and quantum information (POF2-422)$$cPOF2-422$$fPOF II$$x0 000201875 588__ $$aDataset connected to CrossRef, juser.fz-juelich.de 000201875 7001_ $$0P:(DE-HGF)0$$aGliga, Sebastian$$b1 000201875 7001_ $$0P:(DE-Juel1)130709$$aHertel, Riccardo$$b2$$eCorresponding Author 000201875 773__ $$0PERI:(DE-600)1479000-2$$a10.1016/j.jmmm.2014.02.097$$gVol. 362, p. 7 - 13$$p7 - 13$$tJournal of magnetism and magnetic materials$$v362$$x0304-8853$$y2014 000201875 8564_ $$uhttps://juser.fz-juelich.de/record/201875/files/1-s2.0-S0304885314002212-main.pdf$$yRestricted 000201875 8564_ $$uhttps://juser.fz-juelich.de/record/201875/files/1402.1142v1.pdf$$yOpenAccess 000201875 8564_ $$uhttps://juser.fz-juelich.de/record/201875/files/1-s2.0-S0304885314002212-main.gif?subformat=icon$$xicon$$yRestricted 000201875 8564_ $$uhttps://juser.fz-juelich.de/record/201875/files/1-s2.0-S0304885314002212-main.jpg?subformat=icon-1440$$xicon-1440$$yRestricted 000201875 8564_ $$uhttps://juser.fz-juelich.de/record/201875/files/1-s2.0-S0304885314002212-main.jpg?subformat=icon-180$$xicon-180$$yRestricted 000201875 8564_ $$uhttps://juser.fz-juelich.de/record/201875/files/1-s2.0-S0304885314002212-main.jpg?subformat=icon-640$$xicon-640$$yRestricted 000201875 8564_ $$uhttps://juser.fz-juelich.de/record/201875/files/1-s2.0-S0304885314002212-main.pdf?subformat=pdfa$$xpdfa$$yRestricted 000201875 8564_ $$uhttps://juser.fz-juelich.de/record/201875/files/1402.1142v1.gif?subformat=icon$$xicon$$yOpenAccess 000201875 8564_ $$uhttps://juser.fz-juelich.de/record/201875/files/1402.1142v1.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000201875 8564_ $$uhttps://juser.fz-juelich.de/record/201875/files/1402.1142v1.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000201875 8564_ $$uhttps://juser.fz-juelich.de/record/201875/files/1402.1142v1.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000201875 909CO $$ooai:juser.fz-juelich.de:201875$$pdnbdelivery$$pVDB$$pdriver$$popen_access$$popenaire 000201875 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130503$$aForschungszentrum Jülich GmbH$$b0$$kFZJ 000201875 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130709$$aForschungszentrum Jülich GmbH$$b2$$kFZJ 000201875 9132_ $$0G:(DE-HGF)POF3-522$$1G:(DE-HGF)POF3-520$$2G:(DE-HGF)POF3-500$$aDE-HGF$$bKey Technologies$$lFuture Information Technology - Fundamentals, Novel Concepts and Energy Efficiency (FIT)$$vControlling Spin-Based Phenomena$$x0 000201875 9131_ $$0G:(DE-HGF)POF2-422$$1G:(DE-HGF)POF2-420$$2G:(DE-HGF)POF2-400$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bSchlüsseltechnologien$$lGrundlagen zukünftiger Informationstechnologien$$vSpin-based and quantum information$$x0 000201875 9141_ $$y2015 000201875 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000201875 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR 000201875 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000201875 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000201875 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000201875 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000201875 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000201875 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000201875 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000201875 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000201875 9201_ $$0I:(DE-Juel1)PGI-6-20110106$$kPGI-6$$lElektronische Eigenschaften$$x0 000201875 980__ $$ajournal 000201875 980__ $$aVDB 000201875 980__ $$aUNRESTRICTED 000201875 980__ $$aI:(DE-Juel1)PGI-6-20110106 000201875 9801_ $$aFullTexts
