Abstract
We report the spin-dependent magneto-transport in chemically homogeneous we akly coupled nickel films above their conductance percolation threshold. Th is is a new type of GMR system free of a non-magnetic spacer where a sharp reversal of local magnetic moments is achieved by dimensional confinement. Magnetoresistance increases with the films resistivity in a remarkable simi larity to the tunnel-type GMR systems.
