The spin-wave energy spectrum and transition temperature of the two-dimensional VSe-like: a retarded Green's function method study.

Based on the recent discovery of intrinsic magnetism in monolayer films VSe, we have constructed a two-dimensional (2D) Heisenberg model incorporating the 1and 2structures. These configurations consist of three layers: the upper and lower surface layers and a middle layer. Using the retarded Green's function method, we investigate the spin-wave energy spectrum, spin-wave density of states, and transition temperature of the system.
