Absztrakt:
We present a theoretical study of elastic spin-dependent
electron
scattering caused by a nonuniform Rashba spin-orbit coupling
strength.
Using the spin-generalized method of partial waves the complete
scattering wave function is derived exactly for the case of a
circular
scattering region. The asymptotic properties of the wave
function and
its behavior close to the scattering center are investigated. In
both
of these regimes we show that an unpolarized incoming beam
becomes
almost fully polarized around the direction of forward
scattering. This
feature could be utilized in spintronic devices.
