On the origin of the positive Hall coefficient in disordered TE-TL alloys
The authors have collected and analysed the available data for the Hall effect and its dependence upon temperature in amorphous Zr-Co, Zr-Ni, Zr-Cu and Ti-Cu alloys. The differences between the measured Hall coefficients, Rh, and the suggested free electron values, R0, have very similar dependences on the number of electrons in the early transition (TE) metal d band. At temperatures higher than those at which quantum corrections are important, RH-R0 is either constant (within the experimental error) or decreases slowly with the increasing temperature as the resistivity does. These observations are consistent with the proposition that in these alloys the positive Hall coefficient is due to the spin-orbit effect.
