ABSTRACT

RESUMEN

In this paper, we show how chiral materials are realized by embedding chiral objects (helices) in an isotropic medium. More precisely, we derive the Drude--Born--Fedorov constitutive relations, governing the propagation of electromagnetic waves in chiral media, from the standard constitutive relations for a homogeneous, isotropic medium by embedding in the medium a large number of regularly spaced, ramdomly oriented helical conductors, each modeled as a dipole.

Resumen
We consider the interlayer exchange coupling between two ferromagnetic layers mediated by a nonmagnetic spacer layer. We adopt the theoretical model which is based on a macroscopic description using the Landau--Lifshitz equations and the Hoffmann boundary conditions characterizing the interlayer exchange coupling between the interfaces of the ferromagnetic films. An asymptotic study of such a layered system for either small or large spacer thicknesses is presented. The asymptotic problem and the boundary conditions at interfaces both for the magnetization and the magnetic field are characterized. Key words. thin films, magnetic multilayers, bilinear coupling, Hoffmann's boundary condition, thin and thick nonmagnetic spacers
