|Abstract:||The magnetotransport properties of antirectangular arrays (2×10 μ m2) embedded into 200-Å -thick continuous Ni80 Fe20 films with the interhole spacing equal to 2 μm have been investigated. We observed that the inhomogeneous current-density distribution, due to the placement of electrical contacts, caused an unusual positive magnetoresistance (MR) behavior for the in-plane longitudinal measurements. Finite element simulations on current-density distribution are in agreement with experimental data on small area antirectangular structures. For the continuous film, however, the current-density distribution does not play a significant role in determining the shape of the MR curve. © 2005 American Institute of Physics.|
