Abstract:
We present a study of the magnetic ground state properties of β-Mn metal alloyed with Co, using neutron polarization analysis of the diffuse neutron scattering cross-section. We analyse the magnetic structure obtained using a reverse Monte Carlo procedure to extract the Mn-Mn spin correlations. The addition of Co leads to a static disordered magnetic structure with medium-range correlations. Our analysis of the spin correlations indicates that both 8c and 12d non-equivalent lattice sites present in the β-Mn structure contribute to the magnetic ground state, where previously it was thought that the 8c site was non-magnetic.

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
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.
