We found that a state with radial orientation of the magnetization prevails at remanence. The evaluation of the magnetoelastic, magnetocrystalline and magnetostatic energies shows that a value as low as 1.5 × 10-3 for the anisotropic relaxation of the in-plane strain components is enough to induce an effective radial easy magnetization direction.2013http://zaguan.unizar.es/record/6150710.1140/epjb/e2013-30935-4http://zaguan.unizar.es/record/61507oai:zaguan.unizar.es:61507info:eu-repo/grantAgreement/ES/DGA/E81info:eu-repo/grantAgreement/ES/DGA/PI049-08info:eu-repo/grantAgreement/ES/MINECO/MAT2009-10040EUROPEAN PHYSICAL JOURNAL B 86, 4 (2013), 134 [7 pp.]All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
