Regulated magnetic interactions in semiconductor nanometer structure have a strong application background in spin electronics and quantum information processing. This paper mainly studies the influence of electron interaction on the magnetic coupling between diluted magnetic semiconductor quantum dots embedded in semiconductors. Taking into account the interaction between electrons, we will calculate the RKKY Magnetic interaction between the local spins of two diluted magnetic semiconductor quantum dots embedded in the semiconductor applying the Keldysh Green’s function method. For the electronic interaction, we use the simple self-consistent mean-field approximation.

半导体纳米结构中调节的磁相互作用在自旋电子学和量子信息处理中具有强大的应用背景。本文主要研究电子相互作用对嵌入半导体中的稀磁半导体量子点之间的磁耦合的影响。考虑到电子之间的相互作用，我们将使用Keldysh Green函数法计算嵌入在半导体中的两个稀释磁性半导体量子点的局部自旋之间的RKKY磁性相互作用。对于电子交互，我们使用简单的自洽平均场近似。
