The resistivity of ferromagnetic metals depends strongly on electron
scattering by spin disorder caused by finite temperature. We have
developed a method for calculation of this part of resistivity from
first principles, i.e., without adjustable parameters. Our approach is
based on the representation of the system by a set of disordered magnetic
moments (the so-called disordered local moment method, DLM). Using a unified
model of electronic structure, we systematically calculated the contribution
of disordered spins for a broad class of ferromagnets including the
elemental ferromagnets (Fe, Co, Ni), ordered intermetallics Ni3Mn and Fe3Si,
selected rare earths (Gd - Tm), and Heusler alloys Ni2MnX, X=In, Sn,Sb.
In all cases we have found a satisfactory agreement with eperimental data.
