Phys. Rev. Lett. 93, 206602 (2004) [4 pages]Berry Curvature on the Fermi Surface: Anomalous Hall Effect as a Topological Fermi-Liquid PropertyReceived 28 June 2004; revised 20 October 2004; published 11 November 2004 The intrinsic anomalous Hall effect in metallic ferromagnets is shown to be controlled by Berry phases accumulated by adiabatic motion of quasiparticles on the Fermi surface, and is purely a Fermi-liquid property, not a bulk Fermi sea property like Landau diamagnetism, as has been previously supposed. Berry phases are a new topological ingredient that must be added to Landau Fermi-liquid theory in the presence of broken inversion or time-reversal symmetry. © 2004 The American Physical Society URL:
