Influence of the shape and surface oxidation in the magnetization reversal of thin iron nanowires grown by focused electron beam induced deposition 2015 Access copy available to the general public Unrestricted Iron nanostructures grown by focused electron beam induced deposition (FEBID) are promising for applications in magnetic sensing, storage and logic. Such applications require a precise design and determination of the coercive field (HC), which depends on the shape of the nanostructure. In the present work, we have used the Fe2(CO)9 precursor to grow iron nanowires by FEBID in the thickness range from 10 to 45 nm and width range from 50 to 500 nm. These nanowires exhibit an Fe content between 80 and 85%, thus giving a high ferromagnetic signal. Magneto-optical Kerr characterization indicates that HC decreases for increasing thickness and width, providing a route to control the magnetization reversal field through the modification of the nanowire dimen- sions. Transmission electron microscopy experiments indicate that these wires have a bell-type shape with a surface oxide layer of about 5 nm. Such features are decisive in the actual value of HC as micromagnetic simulations demonstrate. These results will help to make appropriate designs of magnetic nanowires grown by FEBID. info:eu-repo/grantAgreement/ES/MINECO/MAT2011-27553-C02 info:eu-repo/grantAgreement/ES/MINECO/MAT2011-28532-C03-02 info:eu-repo/grantAgreement/ES/MINECO/MAT2014-51982-C2-1-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.778 2015 MATERIALS SCIENCE, MULTIDISCIPLINARY 61 / 271 = 0.225 2015 Q1 T1 PHYSICS, APPLIED 30 / 145 = 0.207 2015 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 34 / 83 = 0.41 2015 Q2 T2 1.001 2015 Electrical and Electronic Engineering 2015 Q1 Physics and Astronomy (miscellaneous) 2015 Q1 Materials Science (miscellaneous) 2015 Q1 Nanoscience and Nanotechnology 2015 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Deen, L.
