  • The complex internal structure of magnetic impurities, which locally distort superconductivity, is usually neglected. Here, Choiet al. report that the number and shape of Shiba states are correlated to the spin-polarized atomic orbitals of the impurity, valuable to design atomic-scale superconducting devices.

  • Understanding the magnetic properties of molecules at the atomic level is a crucial aspect in the growing area of organic spintronics. This study brings further insight into the mechanisms of electron-spin interactions by investigating an iron-based organic molecule deposited on gold substrates.

  • Metallocene molecules are known to fragment upon surface deposition, leading to complex molecular reorganization during surface adsorption. Here, thermally-induced nickelocene fragmentation is observed on Au(111), where NiCp fragments self-assemble into 1D chains, suggesting temperature-driven molecular dissociation as a potential route for fabricating surface-assembled nanostructures.
