Abstract
The magnetostatic coupling in lithographically de"ned 25 nm thick Ni

Fe

wire arrays has been investigated using
magnetoresistance (MR) measurements. The structures consist of array of micron-size wires with inter-wire spacings in
the range from 50 nm to 2 m. For the "eld applied along the easy axis of the magnetostatically coupled wire array,
a novel magnetoresistance behaviour is observed which we explain in terms of anti-parallel alignment of magnetisation in
