Recent research in to Carbon Nanotubes filled with magnetic materials has produced someinteresting results that have the potential to bring about new computing technology. In particular one type of system referred to as a nanowire has shown particular promise. However, a deeper understanding of the fundamental magnetic properties is required to fully utilize these materials in novel applications. For the first time new fabrication methods have made it possible to study these systems using the MuSR technique which can provide vital information about the origins and behavior of the magnetic properties that conventional techniques cannot. Our key objectives in this proposal are to build on the novel result from the first MuSR studies, determine the origin of the magnetic properties and understand the role of the lattice crystal structure on these properties.
