摘要：
The magnetism is calculated for substitutional alloyed of Cr-x(Mn-x)V1-x monolayers (MLs) and CrxMn1-x on V (001) surface with a variety of concentrations (x = 0.25, 0.50 and 0.75). The substitutional surface alloys were treated by an artificial super cell construction. Parallel magnetic ordering is obtained for all the considered structures. The surface net magnetization increases in terms of Cr (Mn) concentration in Cr-x(Mn-x)V1-x /V (001) system, while no serious variations occur in CrxMn1-x/V (001). Vanadium atoms at the interfacial layers acquire appreciable magnetic moments antiferromagneticlly (DeltaF) coupled with the surface moments.
