We study the intrinsic spin Hall effect (SHE) and anomalous Hall effect (AHE) in transition metals. We argue that (1) the intrinsic mechanism can be understood as an orbital Aharonov-Bohm effect and (2) the origin of the SHE and AHE is the “orbital” Hall effect and, based on it, the magnitude and the sign of the SHE and AHE are semiquantitatively understood. The sign change of SHE with the increase of the atomic number predicted by the present theory has recently been confirmed experimentally, implying that the intrinsic mechanism indeed works in transition metals.
