Strain-induced magnetization reorientation in epitaxial Cu/Ni/Cu rings 2013 The role of the strain state in epitaxial (001)-oriented Cu/Ni(14 nm)/Cu rings is investigated using a combination of magnetic force microscopy and finite-element calculations. 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. info:eu-repo/grantAgreement/ES/DGA/E81 info:eu-repo/grantAgreement/ES/DGA/PI049-08 info:eu-repo/grantAgreement/ES/MINECO/MAT2009-10040 info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.664 2013 PHYSICS, CONDENSED MATTER 14 / 67 = 0.209 2013 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Coffey, D.
