dc.description.abstract | We have investigated tunneling interlayer exchange coupling (TIEC) between ferrimagnetic
Fe3O4 ?lms via a tunneling barrier. In this investigation we employ ab-initio density functional
theory to study a generic tunneling junction incorporating ferrimagnets Fe3O4/vac/Fe3O4. In
contrast with previously established TIEC theory calculated here thickness dependence is non-
monotonic and accompanied by TIEC sign change. Our calculations clearly demonstrate that
TIEC is controlled mainly by an interfacial oxygen induced spin polarization. These results em-
phasize importance of localized and strongly directional electronic interactions at the interface,
thus showing limitations of free electron model treatment of the problem. | en |
