Effect of the structure of cobalt nanocrystal organization on the collective magnetic properties
The magnetic properties of 8-nm cobalt nanocrystals that have been deposited on a highly oriented pyrolytic graphite substrate and either organized in lines or in the form of a film with local ordering are compared. Collective properties governed by dipolar interactions and due to the nanocrystal organization in lines are demonstrated.
