- Abstract: We utilize simulations of spin-polarized electron scattering by a chain of
localized quantum spins to show that energy and linear momentum conservation
laws impose strong constraints on the properties of magnetic excitations
induced by spin transfer. In turn, electron's orbital and spin dynamics depends
on the dynamical characteristics of the local spins. Our results suggest the
possibility to achieve precise control of spin transfer-driven magnetization
dynamics by tailoring the spectral characteristics of the magnetic systems and
the driving electrons.
