英文摘要	Two-dimensional (2D) magnetic kagome lattices are constructed using silicon carbide triangular nanoflakes (SiC-TNFs). Two types of structures with alternating Si and C atoms are studied: the first one is constructed using the C-edged SiC-TNFs as the building blocks and C atoms as the linkers of kagome sites (TNFN-C-TNFN) while the second one is composed of the Si-edged SiC-TNFs with Si atoms as linkers (TNFN-Si-TNFN). Using density functional theory-based calculations, we show that the fully relaxed TNFN-C-TNFN retains the morphology of regular kagome lattice and is ferromagnetism. On the other hand, the TNFN-Si-TNFN structure is deformed and antiferromagnetic. However, the ground state of TNFN-Si-TNFN structure can be transformed from the antiferromagnetic to ferromagnetic state by applying tensile strain. Monte Carlo simulations indicate that the SiC-TNFs-based kagome lattices can be ferromagnetic at room temperature.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000307273400069&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Multidisciplinary; Nanoscience & Nanotechnology; Materials Science, Multidisciplinary; SCI(E); EI; 2; ARTICLE; 8; 14
