Abstract
The various theories of the skew-scattering contribution to the extraordinary Hall effect are reviewed and several numerical discrepancies are pointed out. It is shown that, except for unit spin polarization, the over-all skew-scattering effect is the sum of two terms: a quantum contribution, which is the basic effect, and a statistical correction, which occurs when Fermi-Dirac statistics are used for the electron gas. This statistical correction, missed by some authors, explains the numerical discrepancies previously mentioned and permits one to bring into concordance the results of the various theories.
