Inhaltszusammenfassung
We perform a first principles calculation of the anomalous Hall effect in ferromagnetic bcc fe. our theory identifies an intrinsic contribution to the anomalous hall conductivity and relates it to the k-space berry phase of occupied bloch states. this dc conductivity has the same origin as the well-known magneto-optical effect, and our result accounts for experimental measurement on fe crystals with no adjustable parameters.
