Quasiclassical size effects for the extraordinary Hall effect in magnetic sandwiches
Résumé
A theory for the extraordinary Hall effect is derived for a magnetic sandwich with antiparallel magnetizations. We use the Kubo formalism to calculate the skew-scattering contribution to the Hall resistivity for both the current perpendicular to the plane and current in the plane geometries. Results indicate strong nonlinearities of the size effect as a function of thicknesses.
