Comparison of experimental results with the theory of the electrical resistivity of ferromagnetic rare earth alloys suggests a rapid redistribution of the scattered conduction electrons over the two spin orientations. In order to investigate whether this effect might be due to the Coulomb interaction between the conduction electrons, the mean free path for depolarization is calculated. In the Born approximation, the mean free path is of the order of some centimeters, whereas the mean free path for scattering is about 50 Å.
