Modification of domain-wall propagation in Co nanowires via Ga+ irradiation 2013 Access copy available to the general public Unrestricted The propagation of domain walls in polycrystalline Co nanowires grown by focused-electron-beam-induced deposition is explored. We have found that Ga+ irradiation via focused ion beam is a suitable method to modify the propagation field of domain walls in magnetic conduits. Magneto-optical Kerr effect measurements show that global Ga+ irradiation of the nanowires increases the domain-wall propagation field. Additionally, we have observed by means of scanning transmission X-ray microscopy that it is possible to produce substantial domain-wall pinning via local Ga+ irradiation of a narrow region of the nanowire. In both cases, Ga+ doses of the order of 1016 ions/cm2 are required to produce such effects. These results pave the way for the controlled manipulation of domain walls in Co nanowires via Ga+ irradiation. info:eu-repo/grantAgreement/ES/MINECO/MAT2011-27553-C02 info:eu-repo/grantAgreement/EC/FP7/251698/EU/Fabrication of three dimensional magnetic nanowires for information storage/3DMAGNANOW info:eu-repo/grantAgreement/ES/CSIC/i-LINK026 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 1.463 2013 PHYSICS, CONDENSED MATTER 42 / 67 = 0.627 2013 Q3 T2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Fernández-Pacheco, A.
