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.
