[en] We consider an extrinsic contribution to the anomalous and spin Hall effect in dilute alloys
based on Fe, Co, Ni, and Pt hosts with different substitutional impurities. It is shown that
a strong skew-scattering mechanism is absent in such crystals with multi-sheeted Fermi
surfaces. Based on this finding, we conclude on the mutual exclusion of strong intrinsic and
skew-scattering contributions to the considered transport phenomena. It also allows us to draw
general conclusions in which materials with a giant anomalous Hall effect caused by the skew
scattering can be achieved.
