The authors have measured the normal Hall effect at liquid helium temperatures for about 250 binary and ternary nickel-based alloys. The results are analysed in terms of the two (spin) current model. For the minority spin band the Hall effect coefficient equals R⁰_spin _down=-6*10^-13 Omega cm G^-1, independent both of the type of impurity and the impurity concentration. For the majority spin current, too, the Hall coefficient does not depend much on the type of impurity, but it strongly varies with rho ^spin ^up, the total resistivity for majority spin carriers.
