Theory of interlayer exchange interactions in magnetic multilayers
This paper presents a review of the phenomenon of interlayer exchange coupling in magnetic multilayers. The emphasis is put on a pedagogical presentation of the mechanism of the phenomenon, which has been successfully explained in terms of a spin-dependent quantum confinement effect. The theoretical predictions are discussed in connection with corresponding experimental investigations.

متن کاملThe combined effect of temperature and disorder on interlayer exchange coupling in magnetic multilayers
We study the combined effect of temperature and disorder in the spacer on the interlayer exchange coupling. The temperature dependence is treated on ab initio level. We employ the spin-polarized surface Green function technique within the tight-binding linear muffin-tin orbital method and the Lloyd formulation of the IEC. The integrals involving the Fermi-Dirac distribution are calculated using...
متن کاملExchange Coupling in Magnetic Multilayers
In magnetic multilayers, the magnetizations of two ferromagnetic layers separated by a non-magnetic spacer layer are coupled by the electrons in the spacer layer. This coupling oscillates in sign as a function of the thickness of the spacer layer. Extensive research done on these systems has led to a simple model for this coupling and remarkable agreement between predictions of the model and me...
متن کاملInterlayer exchange coupling in (Ga,Mn)As based multilayers
The exciting new prospect of spin based electronics, known as spintronics, was initiated in 1988 with the discovery of giant magnetoresistance (GMR) in metallic multilayer structures [1, 2]. These structures consist of interposed ferromagnetic (FM) and non-FM layers. When adjacent FM layers are aligned in antiparallel directions, enhanced spin scattering of carriers causes an increased electric...
