Abstract:
Recent advances in the orthogonal-dimer spin-Heisenberg antiferromagnet are reviewed. This model has been examined for more than 40 years since it was originally studied by Shastry and Sutherland. The discovery of SrCu(BO)as a good candidate material for thesystem led to a considerable advancement in subsequent research. In the case whenis larger than 1/2, however, the elucidation of the properties of the system was relatively delayed. In the ground state of general-systems, interesting quantum phase transitions occur not only for. In this article, the systematic behavior depending onwhich has been recently clarified by unbiased and numerical computational calculations is reviewed. The effects due to spin anisotropy as determined from experimental and theoretical results are also overviewed. We also mention recent developments for thesystem.

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.
