论文摘要
我们利用局部量子旋转链对自旋电子散射进行模拟，以表明能量和线性动量保护定律对通过自旋转移引起的磁激发的特性施加了强大的约束。反过来，电子的轨道和自旋动力学取决于局部自旋的动力学特性。我们的结果表明，通过调整磁系统和驱动电子的光谱特性，可以精确控制自旋传递驱动的磁化动力学。
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.
