Transition metal (e.g., Ni, Co, Ti)-fullerene (C(60)) hybrid composites represent interesting materials which exhibit unusual properties, e. g., charged transfer, spontaneous self-organization, biocompatibility, etc. It is of basic interest to inspect the properties of the hybrid systems, including their structural integrity and relaxation proclivity. In this work, we report on a slow-paced transformation of the Ni + C(60) thin film in ambient atmosphere at room temperature. The Ni + C(60) system was synthesized on the Si(1 1 1) wafer as a supersaturated composite of two immiscible phases. Because of high internal stress, the Ni + C(60) binary system was disposed to structural relaxation that resulted in a moderate alteration of its surface morphology.
