|Issue Date:||May-2004||Citation:||Wang, C.C., Adeyeye, A.O., Lin, C.C. (2004-05). Magnetic properties of lithographically defined rectangular antidot permalloy arrays. Journal of Magnetism and Magnetic Materials 272-276 (SUPPL. 1) : e1299-e1300.

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.
