Local tunneling magnetoresistance control with surface-state confinement and external electric field
Physical Review B 86, (4),pp 045409/1-5 (2012)
On the basis of density functional calculations, the possibility of using spin-polarized confinement and band structure manipulation by means of external electric fields to tune the local spin polarization of electrons and the local magnetoresistance ratio of a tunneling junction is discussed. To illustrate the concept, a model system of a bilayer Co island supported on a Cu(111) surface is used.
