English abstract:
The paramagnetic spin-disorder resistivity (SDR) of transition-metal ferromagnets Fe, Co, Ni, ordered
transition metal alloys Ni3Mn and Fe3Si as well as Ni2MnX (X = In,Sn,Sb) Heusler alloys is determined from
first principles. SDR is evaluated similar to the residual resistivity by using the disordered local moment (DLM)
model combined with the Kubo-Greenwood linear response calculation. The electronic structure is determined
within the tight-binding linear muffin-tin orbital method and the coherent potential approximation (CPA) applied
to the DLM state. We also estimate the temperature dependence of the resistivity below the Curie temperature
using a simple model. The results agree well with the supercell Landauer-Bšuttiker calculations and, generally,
with experimental data. For the Ni2MnSb Heusler alloy it is necessary to include substitutional disorder of
B2-type to explain the experimental data.
