Extraordinary Hall effect (EHE) and Magnetoresistance (MR) were measured on
a set of granular CoxCu100-x films prepared in the same run by electron-be
am evaporation in a wide range of compositions (10 < x < 70). It is shown t
hat near the percolation threshold a sharp drop of magnetic scattering occu
rs in these films. (C) 1999 Elsevier Science B.V. All rights reserved.
