Abstract:
Spin interactions between magnetic molecules and substrates are of fundamental importance, as they offer key insights into spin-related phenomena and underpin the development of energy-efficient spintronic devices. Transition-metal phthalocyanine (TMPc) molecules serve as exemplary model systems for probing these interactions, owing to their high structural stability, tunable magnetic moments, and well-defined local environment. When adsorbed on different substrates, TMPc molecules can exhibit a rich variety of spin-related phenomena including the Kondo effect, spin excitations, and Yu-Shiba-Rusinov (YSR) states, which can be directly resolved by scanning tunnelling microscopy (STM). This review summarizes recent STM advances on the coexistence and competition of spin-related phenomena in TMPc adsorbates, emphasizing the underlying mechanisms and practical control strategies enabled by chemical design and electric- and magnetic-field stimuli, and concludes with an outlook on emerging directions for future research.

03:02Colors 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...

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.
