| 中文摘要 | We investigate the surface magnetism of the alternating superlattice with localized spin-1/2. Using the mean-field approximation method, we discuss not only the correlation between file critical value j(0C) of the exchange constant in the Surface layer and interlayer exchange constants. but also the connection between j(0C), and the bulk exchange constant j(A). The calculated results are in good agreement with the former theoretical calculations. Based oil the Solutions, we show the relations between the critical parameter c = J(S)/J(A) and the bulk exchange constants as well as file Surface transition temperature. J(S) is the exchange constant in the first two surface layers. Comparing with the earlier theoretical works. Our results show the effect of the Surface modification more gradual. |
