Abstract:
We systematically investigated the magnetic properties of a single crystal bulk Fe3O4 at low temperatures. Below Verwey transition, the magnetization versus temperature curves under zero-field cooling present anomalous behaviors for [1 0 0], [1 0 1] and [0 0 1] directions, respectively. Furthermore, at Verwey temperature, a high sensitivity of relative magnetization change (ΔM/M) to small magnetic field and, in particular, a reversal of ΔM/M at moderate magnetic field range for [0 0 1] direction is observed. Our work demonstrates a very important role of magnetic axis reorientation effect in low temperature magnetic properties of magnetite, which will stimulate further research on the intricate microscopic physics mechanisms in this classic material.

Magnetic Susceptibility and Permeability
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...

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....
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...
