چکیده
|
Scattering matrix formalism is employed to calculate the spin transfer torque in a graphene-based domain wall (dw) in the ballistic regime. we have suggested a new method for manipulating the direction of domain wall motion by both the length of the dw and magnetic barrier that is the ratio of induced exchange field to fermi energy. it has also shown that spin current density gives us more insight into the transmission of spin-polarized electrons.

Abstract
|
scattering matrix formalism is employed to calculate the spin transfer torque in a graphene-based domain wall (dw) in the ballistic regime. we have suggested a new method for manipulating the direction of domain wall motion by both the length of the dw and magnetic barrier that is the ratio of induced exchange field to fermi energy. it has also shown that spin current density gives us more insight into the transmission of spin-polarized electrons.
