TL;DR: Co/Au(788) thus constitutes an ideal model system to explore the ultimate density limit of magnetic recording and shows the absence of magnetic interactions between the particles.

TL;DR: In this paper, a combination of scanning tunnelling microscopy measurements and ab initio calculations allows discriminating unambiguously between two spin states by local vibrational spectroscopy, and a single layer of spin cross-over molecules in contact with a metallic surface displays light-induced collective processes between two ordered mixed spin-state phases with two distinct timescale dynamics.

TL;DR: It is demonstrated that a C(60) overlayer enhances the perpendicular magnetic anisotropy of a Co thin film, inducing an inverse spin reorientation transition from in plane to out of plane.

TL;DR: The comparison between tunneling and angle-resolved photoelectron spectra reveals the spatial inhomogeneity of the Dirac energy shift and that a phonon correction has to be applied to the tunneling measurements, and XPS data demonstrate the dependence of the N 1s binding energy of graphitic nitrogen on the nitrogen concentration.

TL;DR: It is demonstrated that a combination of scanning tunnelling microscopy measurements and ab initio calculations allows discriminating unambiguously between both states by local vibrational spectroscopy, which opens a way to molecular scale control of two-dimensional spin cross-over layers.
