平行磁场中二维电子气自旋-轨道相互作用的Friedel振荡

Friedel oscillations in 2D electron gas from spin-orbit interaction in a parallel magnetic field

I. V. Kozlov, Yu. A. Kolesnichenko

摘要:

研究了在平行磁场作用下,具有Rashba-Dresselhaus自旋轨道相互作用的二维电子气中磁点缺陷周围电子波的干涉效应.分析了磁场对局域态密度和局域磁化强度的各向异性空间分布的影响。的磁化强度与散射的非磁性缺陷和磁散射(伴随着自旋翻转)在局部电子态密度的贡献的密度的振荡的存在进行了预测。

英文摘要:

Effects associated with the interference of electron waves around a magnetic point defect in two-dimensional electron gas with combined Rashba-Dresselhaus spin-orbit interaction in the presence of a parallel magnetic field are theoretically investigated. The effect of a magnetic field on the anisotropic spatial distribution of the local density of states and the local density of magnetization is analyzed. The existence of oscillations of the density of magnetization with scattering by a non-magnetic defect and the contribution of magnetic scattering (accompanied by spin-flip) in the local density of electron states are predicted.
