Abstract:
We present a study of the structural, magnetic, transport, and thermal properties for the polycrystalline intermetallic compound CeCo2Al8which crystallizes in orthorhombic structure, space groupPbam. X-ray photoelectron spectroscopy confirms that cerium is in the trivalent state in this compound. Low-temperature magnetic correlations with possible short-range antiferromagnetic ordering below ∼ 4 K are observed. Temperature and field dependent electrical resistivity measurements indicate deviation from metallic behavior. The low-temperature specific heat of CeCo2Al8exhibits -log T upturn in the electronic specific heat below ∼10 K, which is a hallmark of Kondo correlations and strongly correlated electron behavior. Considering all these properties, CeCo2Al8behaves as a moderate Kondo lattice system due to moderate coupling between trivalent cerium and cobalt ions.

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...
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.
