摘要：
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 GdCl3 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. (c) 2022 Elsevier Ltd. All rights reserved.
