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.2014http://zaguan.unizar.es/record/5783610.1103/PhysRevB.89.144405http://zaguan.unizar.es/record/57836oai:zaguan.unizar.es:57836info:eu-repo/grantAgreement/ES/MINECO/FIS2010-20979-C02-02info:eu-repo/grantAgreement/ES/MINECO/MAT2011-23791info:eu-repo/grantAgreement/ES/MINECO/MAT2012-36844info:eu-repo/grantAgreement/ES/MINECO/MAT2012-38318-C03-03Physical Review B.
