Confinement mechanism for strong temperature dependence of the interlayer exchange coupling in Co/Cu(001)
1996
Physical Review B (Condensed Matter)
Preserved Fulltext
It is shown, within the quantum-well theory of the exchange coupling J in magnetic multilayers, that the temperature dependence of J is governed not only by the spacer Fermi surface but also by the confining strength of the ferromagnetic layers. The confinement mechanism is first explored for an exactly solvable parabolic-band model and cases in which it leads to a very strong temperature dependence of J are identified. Finally, it is demonstrated, using fully realistic tight-binding bands,
