论文摘要
二维磁铁对于纳米级的旋转器应用有希望。目前，大多数可用的候选人基于$ 3D $过渡金属化合物，具有六角形或蜂窝晶格几何形状。在这里，理论上研究了带有$ 4F $矩的GDCL $ _3 $单层，可以从其现有的体积中删除。它的矫正结构和hendecahedral离子笼在二维中是独一无二的。此外，重要的结构重建是由将Li原子植入其间质位置引起的，这也通过双交换样过程导致铁磁学。它的高度各向异性电导对于纳米电子学可能非常有用。
Two-dimensional magnets are promising for nanoscale spintronic applications. Currently, most available candidates are based on $3d$ transition metal compounds, with hexagonal or honeycomb lattice geometry. Here, a GdCl$_3$ monolayer with $4f$ moments is theoretically studied, which can be exfoliated from its existing bulk. Its orthorhombic structure and hendecahedral ion cages are unique in two-dimensional. Furthermore, a significant structural reconstruction is caused by the implantation of Li atoms into its interstitial position, which also lead to ferromagnetism via a double-exchange-like process. Its highly anisotropic conductance may be peculiarly useful for nanoelectronics.
