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.
