Non-RKKY oscillations of exchange coupling in magnetic multilayers
M. S. Ferreira, J. d'Albuquerque e Castro, D. M. Edwards +1
It is shown how the exchange coupling between two ferromagnetic planes embedded in an infinite non-magnetic metal, regarded as a function of the distance between the planes, may co…
Superconductivity in the two dimensional Hubbard Model.
J. Beenen, D. M. Edwards
Quasiparticle bands of the two-dimensional Hubbard model are calculated using the Roth two-pole approximation to the one particle Green's function. Excellent agreement is obtained…
The Nature and Validity of the RKKY limit of exchange coupling in magnetic trilayers
M. S. Ferreira, R. B. Muniz, J. d'Albuquerque e Castro +1
The effects on the exchange coupling in magnetic trilayers due to the presence of a spin-independent potential well are investigated. It is shown that within the RKKY theory no bia…
