Surface magnetism in vanadium overlayers on W(100) -

Localized surface magnetism in materials with non-magnetic bulk is a subject of considerable interest. In particular, in the case of strained transition metal overlayers on transition metals substrates, the interaction overlayer-substrate can lead to a fascinating magnetic behavior where the competition between strain and hybridization controls spin-polarized states.

Magnetism of free and supported vanadium clusters

May 05, 2020 · The study of magnetism of free V clusters also suffers from the same controversy. An early experiment by Akoh and Tasaki [15] confirmed that small particles of vanadium in the size range 100–1000 atoms are magnetic. However, a recent experiment of Douglass et al [16] found no evidence of magnetism in free V clusters containing as few as 9 atoms.

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

The NMR studies were carried out on the ultra fine particles of vanadium. The observed signal with Knight shift 0.7% might arise form surface region since its intensity increases relatively with decrease of the particle size. The spin-lattice relaxation time of this line maintains the Korringa's relation, which indicates that the surface electrons have still metallic character.
