In this paper, we have inspected the structural morphology of novel composite materials transition metal (TM) (Ni, Ti) / fullerene (C-60) thin films, prepared at room temperature (RT) or 500 degrees C, and modified by ion-irradiation and/or thermal annealing. The hybrid films were synthesized by alternative or simultaneous deposition of the immiscible TM and C-60 phases. As deposited (at RT) the hybrid systems were thermodynamically unstable and the internal stress induced lengthy phase separation. Co-deposition at 500 degrees C resulted in the formation of a large-scale pattern structure. By high temperature annealing of the multilayer's a new morphology could be synthesized. In addition, high-fluence ion-irradiation induces C-60 fragmentation that has a strong impact on the final shaping of the resulted morphology.
