Hybrid Metal-Carbon Nanostructures Next-generation spintronic and data storage devices will be based on nanoscale functional materials such as single-molecule magnets and magnetic nanoparticles. One particular challenge for harnessing the functional properties (magnetic bistability, quantum tunnelling of magnetization, and quantum coherence) of these remarkable nanometer-sized magnetic objects is the coupling to the macroscopic world. Hollow carbon nanostructures such as carbon nanotubes and nanofibers with one macroscopic and two nanoscopic dimensions provide an excellent means to achieve this coupling via encapsulation and confinement of magnetic species in their internal void [1]. Unlike nanotubes, carbon nanofibers through their corrugated interiors allow the controlled arrangement of the nanoscale objects [2,3]. As these passive containers are chemically inert, they represent the most suitable host material for novel hybrid nanostructures where the properties of the guest can either be retained or enhanced depending on synergistic interactions with the host.
