Giant magnetoresistance in cluster-assembled nanostructures:a quantitative approach

摘要

In a recent publication [1] we have discussed qualitatively the applicability of commonly used assumptions and models in the description of giant magnetoresistance in granular media by comparing to well-defined cluster-assembled nanostructures of cobalt clusters embedded in copper thin films.In this article we present a quantitative analysis and discuss the relevant parameters appearing in the model.
