High-sensitivity MFM imaging (with a detection noise of 1 µN m-1) reveals the presence of single-domain structures in remanence with strong contrast at the ends of the nanowires, as well as at the transition regions where the diameter is modulated. Micromagnetic simulations suggest that curling of the magnetization takes place at these transition sites, extending over 10–20 nm and giving rise to stray fields measurable with our MFM. An additional weaker contrast is imaged, which is interpreted to arise from inhomogeneities in the nanowire diameter. 000056197 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/MAT2013-48054-C2-1-R$$9info:eu-repo/grantAgreement/ES/MINECO/CSD2010-00024$$9info:eu-repo/grantAgreement/EC/FP7/280670/EU/RARE EARTH FREE PERMANENT MAGNETS/REFREEPERMAG 000056197 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000056197 590__ $$a3.573$$b2015 000056197 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b50 / 271 = 0.185$$c2015$$dQ1$$eT1 000056197 591__ $$aPHYSICS, APPLIED$$b24 / 145 = 0.166$$c2015$$dQ1$$eT1 000056197 591__ $$aNANOSCIENCE & NANOTECHNOLOGY$$b30 / 83 = 0.361$$c2015$$dQ2$$eT2 000056197 592__ $$a1.257$$b2015 000056197 593__ $$aBioengineering$$c2015$$dQ1 000056197 593__ $$aChemistry (miscellaneous)$$c2015$$dQ1 000056197 593__ $$aElectrical and Electronic Engineering$$c2015$$dQ1 000056197 593__ $$aMaterials Science (miscellaneous)$$c2015$$dQ1 000056197 593__ $$aMechanical Engineering$$c2015$$dQ1 000056197 593__ $$aMechanics of Materials$$c2015$$dQ1 000056197 593__ $$aNanoscience and Nanotechnology$$c2015$$dQ2 000056197 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000056197 700__ $$aBran, C. 000056197 700__ $$aBerganza, E. 000056197 700__ $$aMínguez-Bacho, I. 000056197 700__ $$0(orcid)0000-0002-6761-6171$$aMagén, C.$$uUniversidad de Zaragoza 000056197 700__ $$aVázquez, M. 000056197 700__ $$aAsenjo, A. 000056197 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
