Abstract
The anomalous Hall angle in ferromagnetic alloys contains two contributions, skew scattering and side displacement both of which depend on the source of electrical resistivity: φ an = φ sk + bϱ. Experimental data on φ an for 250 binary and ternary nickel based alloys are analysed in terms of the two-current model. For a large number of solute metals, values for φ ↑ sk and φ ↓ sk are derived. It is observed that the value of b varies systematically with the fraction of the current carri ed by spin-up carriers. The results suggest that φ ↓ sk and b ↓ sk are of the same (positive) sign, while for the opposite spin direct ion they are both negative.
