Effect of spin-flip processes on the Pauli susceptibility

  • Published:
Physik der kondensierten Materie

Abstract

The reduction of the Pauli susceptibility due to a perturbing Hamiltonian which allows for spin-flip processes is calculated. The results are applied to the spin-orbit coupling in liquid metals, and the exchange interaction in magnetic metals at high temperatures and near the Curie point. The corrections are small.

Résumé

On calcule la réduction de la susceptibilité de Pauli provenant d'un Hamiltonien qui est responsable des processus de renversement de spin. Les résultats sont appliqués au couplage spin-orbite dans les métaux liquides ainsi qu'à l'interaction d'échange dans les métaux magnétiques aux hautes températures et dans les environs du point de Curie. Les corrections apportées à la susceptibilité sont petites.

Zusammenfassung

Die Verminderung der Paulisuszeptibilität infolge einer Störung, welche Streuungen mit Spinumkehr ermöglicht, wird berechnet. Das Resultat wird auf die Spin-Bahn-Kopplung in flüssigen Metallen und auf die Austauschwechselwirkung in magnetischen Metallen bei hohen Temperaturen und in der Nähe des Curiepunktes angewandt. Die Korrekturen sind klein.
