Tunable topological phase in 2D ScVSn kagome material
arXiv:2504.18030 · doi:10.1016/j.mtphys.2025.101780
Abstract
We investigate the topological properties of the vanadium-based 2D kagome metal ScVSn, a ferromagnetic material with a magnetic moment of 0.86 per atom. Using ab initio methods, we explore spin-orbit coupling-induced gapped states and identify multiple Weyl-like crossings around the Fermi energy, confirming a Chern number and a large anomalous Hall effect (AHE) of 257 cm. Our calculations reveal a transition from a topological semimetal to a trivial metallic phase at an electric field strength of 0.40 eV/Å. These findings position 2D ScVSn as a promising candidate for applications in modern electronic devices, with its tunable topological phases offering the potential for future innovations in quantum computing and material design.
