We have investigated the field dependence of extraordinary Hall coeffi
cient R-s and resistivity rho in Fe-Ag granular alloys. We found a dev
iation from the linear scaling relation between R-s(H)/rho(H) and rho(
H) in agreement with the results reported for Co-based granular alloys
, suggesting that the deviation from the linear scaling relation is co
mmon to granular systems. (C) 1997 Elsevier Science B.V. All rights re
