【摘要】 The magnetic properties of two-dimensional antiferromagnet NiGa2S4have attracted much attention and yet some problems are far from being solved. We investigate the magnetic properties of NiGa2S4by Monte Carlo simulations. A new spin-interacting model is proposed to describe the system, and the specific heat together with the doping effect of nonmagnetic impurity is studied by simulations. The double peaks of the specific heat as well as other behaviors are well reproduced. We also compare our results with those of other models, and the underlying physics is discussed.
