论文摘要
为了了解Rashba旋转轨道相互作用与铁磁接近效应之间的耦合因子，我们设计了一种蒙特卡洛算法，以在有限温度下模拟室温Rashba材料，石墨烯/镍（111）子材料的旋转和电荷分布。我们观察到，交换速率波动是在石墨烯中产生巨大的Rashba旋转轨道分裂的关键参与者。更重要的是，我们监视了Rashba自旋分裂现象，在加热时可以从两个相对的边缘逃脱自旋偏振电子。但是，逃脱的电子在内部区域显示出高斯样的分布，这对于Spintronic工程师优化自旋状态检测的效率很重要。此外，我们研究了我们的蒙特卡洛模型是否可以解释为什么在石墨烯/镍（111）底物中观察到室温Rashba效应。所有结果均以物理单位呈现。
To understand the coupling factor between Rashba spin-orbital interaction and ferromagnetic proximity effect, we design a Monte Carlo algorithm to simulate the spin and charge distributions for the room-temperature Rashba material, Graphene/Nickel(111) substrate, at finite temperature. We observe that the rate of exchange fluctuation is a key player to produce giant Rashba spin-orbit splitting in graphene. More importantly, we monitor the Rashba spin-splitting phenomenon where the spin-polarized electrons may be escaped from two opposite edges upon heating. However, the escaped electrons show Gaussian-like distribution in interior area that is important for spintronic engineers to optimize the efficiency of spin-state detection. In addition, we investigate if our Monte Carlo model can explain why room-temperature Rashba effect is observed in Graphene/Nickel(111) substrate experimentally. All results are presented in physical units.
