Substrate-Independent Magnetic Bistability in Monolayers of the Single-Molecule Magnet Dy₂ ScN@C₈₀ on Metals and Insulators.

ABSTRACT: Magnetic hysteresis is demonstrated for monolayers of the single-molecule magnet (SMM) Dy₂ ScN@C₈₀ deposited on Au(111), Ag(100), and MgO|Ag(100) surfaces by vacuum sublimation. The topography and electronic structure of Dy₂ ScN@C₈₀ adsorbed on Au(111) were studied by STM. X-ray magnetic CD studies show that the Dy₂ ScN@C₈₀ monolayers exhibit similarly broad magnetic hysteresis independent on the substrate used, but the orientation of the Dy₂ ScN cluster depends strongly on the surface. DFT calculations show that the extent of the electronic interaction of the fullerene molecules with the surface is increasing dramatically from MgO to Au(111) and Ag(100). However, the charge redistribution at the fullerene-surface
