Magnetic antidot to dot crossover in Co and Py nanopatterned thin films 2014 Access copy available to the general public Unrestricted The crossover from antidot to dot magnetic behavior on arrays patterned in a ferromagnetic thin film has been achieved by modifying only the geometry. A series of antidot arrays has been fabricated on cobalt with fixed diameter d and by reducing the period of the array p from p»d to p<d. A dramatic change in the coercivity dependence with p, correlated with a significant modification in the magnetic domain structure observed by x-ray photoemission electron microscopy, evidences the crossover. An intermediate regime has been found between the superdomain structure present in antidot arrays and the array of astroid-state noncorrelated dots. The study has been reproduced for a different ferromagnetic material, permalloy, and supported by micromagnetic simulations. info:eu-repo/grantAgreement/ES/MINECO/FIS2010-20979-C02-02 info:eu-repo/grantAgreement/ES/MINECO/MAT2011-23791 info:eu-repo/grantAgreement/ES/MINECO/MAT2012-36844 info:eu-repo/grantAgreement/ES/MINECO/MAT2012-38318-C03-03 info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 3.736 2014 PHYSICS, CONDENSED MATTER 14 / 66 = 0.212 2014 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-0901-8341 Herrero-Albillos, J.
