论文摘要
使用密度功能理论和电磁计算的组合，考虑了将石墨烯在单层三碘化物（CRI3）石墨烯范德华（VDW）异质结构中的交换分裂和产生的电磁反应。尽管有效的交换场在数百个特斯拉中，但对于平衡分离，与可比的外部磁性偏差相比，发现非相互效应的非相互效应是弱的。对于非平衡分离，非偏置效应可能很大。
The exchange splitting and resulting electromagnetic response of graphene in a monolayer chromium triiodide(CrI3) graphene van der Waals(vdW) heterostructure are considered using a combination of density functional theory and electromagnetic calculations. Although the effective exchange fields are in the hundreds of Tesla, for the equilibrium separation non reciprocal effects are found to be weak compared to those for a comparable external magnetic bias. For non equilibrium separations, nonreciprocal effects can be substantial.
