【 摘 要 】

In this paper, the magnetic properties, thermal spin fluctuation and the spin wave spectra of a 2D tetragonal ferromagnetic monolayer with Heisenberg model including single-ion anisotropy are studied using functional integral method. Influence of exchange interaction at edge on these properties of the monolayer is also considered. The model is applied for a new robust ferromagnetic monolayer with the 2D tetragonal structure, Co2S2, in which the exchange interaction between magnetic atoms and non-magnetic atoms is included due to hybridization between Co 3d states and S 3p states.
