Abstract
Abstract We report the structural, electronic and magnetic properties of zigzag-type 2H-VS 2 nanoribbons based on the first-principles calculations. Our results suggest that the zigzag-type 2H-VS 2 nanoribbons are intrinsic ferromagnetic or ferrimagnetic materials dependent on their edge structures. The S-terminated VS 2 nanoribbons with or without hydrogen saturation at the edges are ferromagnetic, whereas V-terminated VS 2 nanoribbons are ferrimagnetic at their ground states. The average magnetic moment per V atom of VS 2 nanoribbons increases monotonously with their width, but still smaller than that of perfect VS 2 monolayer. These results imply the great potential of VS 2 nanoribbons in spintronics application.
