摘要：
The electronic and magnetic properties of the ground state (T = 0 K) of vanadium islands on Ag(001) were investigated through a mean-field parameterized tight-binding method. The Ag substrate does not affect much the magnetism of the V atoms which is directly related to the V-V coordination number. Therefore, the outermost V atoms present the highest magnetic moment. Antiferromagnetic like coupling is obtained between most of the V atoms at nearest neighboring positions. However, when a vanadium atom is coupled antiferromagnetically to a part of its nearest neighboorhood and ferromagnetically to the other part, its magnetic moment remains very low.
