The spatial variation of coercivity on patterned magneto-optical (MO) materials was studied using a Kerr microscope. As compared with nonpatterned MO media, the coercivity distribution in the patterned material is much wider and shows an exponential-type distribution. The results show that the coercivity values on arrays made by holes are larger than those observed on the land regions.
