Abstract: The results of a study on Co[SiO2] granular films was studied by means of magnetic force microscopy (MFM) and DC magnetization. The MFM studies showed large strip magnetic domains in the percolated system and allowed a direct investigation of the magnetic interaction among grains in the film with the lowest metal volume fraction. The results suggested that the Co critical concentration to create large percolated magnetic domains was close to 0.51.
