Abstract Scope |
The combination of a nanoparticle source with magnetron sputtering opens up plentiful potential for the fabrication of unique nanocomposite thin films. Nanoparticles (NPs) with tailored size, shape, distribution and volume density can be incorporated without precipitation-related re-strictions concerning phase diagrams and solubility. We use this approach to incorporate magnet-ic Co nanoparticles (diameter 10 nm) into a conductive metallic Cu matrix (50-200 nm thickness) on flexible polymer substrates. We study the deformation mechanisms with X-ray diffraction and resistance measurements during in situ tensile testing and test the hypothesis that the static and dynamic magnetic properties are well controlled under strain. Results indicate a clear change in the observed crack pattern with film thickness that corresponds well to the evolution of the elec-trical resistance during straining and the shape of the film stress-strain curves. In summary, the novel nanocomposites are promising candidates for flexible magneto-electronic thin films. |
