Magnetic granular systems have been applied to many fields of study, e.g. spin glass properties or magnetic resistance phenomena. These magnetic granular systems have homogeneous densities of magnetic granules and there physical properties changes depending on its densities. In this study, to investigate magnetic properties of such granular systems, minor hysteresis loops analysis was performed using Monte Carlo simulation. As the granular systems, clusters with various magnetic site densities were prepared by simple diffusion model. Moreover, these clusters were analyzed from new point of view which is a concept of a ``colony''. The results of minor loop analysis were considered associating with colony.
