The resistivity anisotropy in ferromagnetic metals due to spin—orbit interaction is considered with spin correlation taken into account. The obtained temperature dependence of Δρ shows a round peak in accord with experiment. In the critical region d(Δρ)/d t diverges as (— t ) 1—(α + φ) ( t = ( T — T C )/ T C , magnetic field h = 0), where φ is the cross‐over exponent.
