Abstract:
We report the discovery of a new compound, SrCo2TeO6, in which the CoO6 octahedra form a double-chain structure extending along the b-axis. The structure consists of CoO6 octahedra connected via edge-sharing in a honeycomb-like arrangement. We present a detailed investigation into the magnetic properties of the spin-1/2 system SrCo2TeO6 through magnetization and specific heat measurements. Our experimental results reveal two successive long-range antiferromagnetic (AFM) phase transitions are observed at TN1 ∼ 11.6 K and TN2 ∼ 9 K, respectively, which demonstrates that SrCo2TeO6 is a quantum spin system with an effective spin Seff = 1/2 and exhibits a 1/2-like magnetization plateau. Compared with the isostructural CaCo2TeO6, the substitution of Sr results in a significant distortion of the Co-O-Co bond angle, which weakens the dominant antiferromagnetic exchange interaction.

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...

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
