Study of cobalt cluster films deposited by high-rate cluster source — •Björn Gojdka, Stefan Rehders, Viktor Hrkac, Venkata S.K. Chakravadhanula, Vladimir Zaporojtchenko, Thomas Strunskus, and Franz Faupel — University of Kiel, Institute for Materials Science, Kaiserstraße 2, 24143 Kiel

Ferromagnetic nanoparticles have been investigated intensively in the last decade as their properties open up a vast range of applications. In the last few years dedicated sources have been developed for the fabrication of size-selected nanoclusters, some of which are now even commercially available. However, present systems often suffer from high instrumental complexity and low deposition rates. We designed and built a cluster source with low technical complexity to deposit ferromagnetic nanoparticles with high deposition rates up to 100 nm/min. We present a study of nanocluster films which consist of cobalt nanoparticles with an average size of about 10 nm. Individual clusters and cluster films with a thickness of several hundred nanometers were investigated regarding their magnetic properties and morphology. The magnetic properties of the resulting cluster films can be tuned directly by the operation parameters of the cluster source.
