abstract = {Using the Kubo formalism we derived expressions and
implemented the method for calculating the anomalous Hall
conductivity (AHC) in ferromagnets with short-range Gaussian
disorder directly from first-principles electronic structure
of the perfect crystal. We used this method to calculate the
AHC in bcc Fe, fcc Co, L10-FePd, L10-FePt as well as thin
bcc Fe(001) films. Within our approach we can transparently
decompose the conductivity into intrinsic, side jump, and
intrinsic skew-scattering (ISK) contributions. The existence
of ISK, which originates from asymmetric Mott scattering but
is clearly distinguishable from conventional skew scattering
in that it converges to a finite value in clean limit, was
pointed out by Sinitsyn et al. [Phys. Rev. B 75, 045315
(2007)]. Here, we collect all contributions to the AHC in
ferromagnets which result in “scattering-independent”
AHE in clean limit, and analyze their relative magnitude
from first-principles calculations. By comparing our results
to existing experiments we show that the Gaussian disorder
is well suited to model various types of disorder present in
real materials, to some extent including the effect of
temperature. In particular, we show that in addition to
intrinsic and side-jump AHE, the intrinsic skew scattering
can be a major player in determining the magnitude of the
AHE in ferromagnets.},
