Abstract:
A cyanide-bridged 1D Fe2Fe chain exhibits rare dual magnetic bistability: thermal spin-crossover and light-induced single-chain magnet behaviour. Photoirradiation switches the system from a diamagnetic to a magnetically correlated paramagnetic state, featuring slow magnetic relaxation and a notably high coercive field of 0.52 T.

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...

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....
