Abstract
The anomalous Hall effect in epitaxial Fe(110) films grown on GaAs(110) is investigated as a function of both film thickness and temperature. The Berry curvature-induced intrinsic contribution of 996 \(\Omega ^{-1}\hbox { cm}^{-1}\) is determined experimentally for the first time. Together with 821 \(\Omega ^{-1}\hbox { cm}^{-1}\) in Fe(111) and 1100 \(\Omega ^{-1}\hbox { cm}^{-1}\) in Fe(001) obtained earlier, we show unambiguously the anisotropy of the Berry curvature contribution to the anomalous Hall effect in single-crystal Fe.
