We report on the synthesis of hard-magnetically terminated carbon nanotubes (CNT) from multilayer Fe-Pt thin film catalysts via plasma enhanced chemical vapour deposition (PECVD). Although FePt is rarely used as a catalyst for CNT synthesis it is of great interest due its special hard magnetic properties when in the chemically ordered L10 phase. The combination of such highly anisotropic nanomagnets with CNT opens up exciting possibilities to create novel CNT functionalities. The tailored growth of CNT with a hard magnetic particle at their tip is very promising for the realization of nanodevices, for example tips for magnetic force microscopy or magnetically actuated nanoelectronic systems.
