Abstract:
The magnetic properties of a pair V4 atomic clusters embedded in bulk Fe are determined by using a realistic spd-band Hubbard-like model. The spin density distribution is calculated self-consistenly in the unrestricted Hartree-Fock approximation. The local magnetic moments mu(i) are obtained at various atoms i of the cluster and of the surrounding Fe matrix. We consider two different geometrical arrangements for V clusters, collinear (C) and non-collinear (NC). In all the cases studied the magnetic coupling in the interface cluster-matrix is antiferromagnetic, and the ferromagnetic order of the matrix is not broken by the presence of the V atoms, although the local magnetic moments of Fe atoms at the interface cluster-matrix, are reduced respect to Fe bulk magnetization (2.22 microB) about 8%-20%. We compare the results with those of just one V4 atomic cluster embedded in bulk Fe.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

Diamagnetism was discovered by Anton Brugmans in 1778 when he observed that bismuth gets repelled by magnetic fields, thus theorizing that diamagnets get repelled by magnets.
