Rings with an external diameter of 3 and 2 μm and linewidth W larger than 400 nm show two different structures: domains with magnetization oriented in the radial direction exist at the inner and outer radius, separated by an area in the interior of the ring consisting of stripe domains with perpendicular magnetization. The former is the sole magnetic structure observed for W<400 nm. Micromagnetic calculations on narrow-linewidth structures indicate that the radial domain-wall structure consists of elliptical Bloch lines with a shorter and longer length along the tangential and radial directions, respectively. Finite-element calculations show that the anisotropic relaxation of the in-plane strain is larger at the ring inner andouteredgesthanintheinteriorpartoftheringandaccountsforthereorientation of the magnetization direction. 000169409 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E81$$9info:eu-repo/grantAgreement/ES/DGA/PI049-08$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2009-10040 000169409 540__ $$9info:eu-repo/semantics/closedAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000169409 590__ $$a3.664$$b2013 000169409 591__ $$aPHYSICS, CONDENSED MATTER$$b14 / 67 = 0.209$$c2013$$dQ1$$eT1 000169409 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000169409 700__ $$0(orcid)0000-0001-7673-1297$$aCoffey, D. 000169409 700__ $$0(orcid)0000-0003-1930-1455$$aCiria, M.$$uUniversidad de Zaragoza 000169409 700__ $$0(orcid)0000-0002-2624-6004$$aArnaudas, J.
