We observed that the presence of the rectangular hole structures strongly modifies the shape of M-H loops, when compared with the reference continuous film. Specifically, the coercivity increases drastically as the inter-hole spacing is reduced. This is in agreement with our magnetic force microscopy images. Marked changes in both the shape and sign of the magnetoresistance curve were also observed. © 2003 Elsevier B.V.
