Surface magnetism of vanadium-based binary alloys: first principles investigations

Abstract Surface magnetism of vanadium-based disordered binary alloys V-Me (Me=Pd, Mo) has been studied by means of the first-principles LMTO-GF-CPA and fixed spin moment methods in conjunction with statistical Monte-Carlo method. Both systems are nonmagnetic in the bulk. However, we have shown that the (1 0 0) surface of uniformly random alloys is magnetic, and magnetic moment may also be present in segregated V-Mo alloys. The origin of the onset of surface magnetism in the studied alloys is analyzed.
