Electron-Induced Spin Crossover

This lecture covers experiments and theory related to molecules at surfaces, focusing on spin states, geometry changes, and current shot noise. It explores spin switching mechanisms, high and low spin states, and electron-induced excited spin state trapping in STM. The presentation delves into the spin state effects on adsorbed molecules, the geometry change between high and low spin states, and the spin switching via axial-coordination in complexes on metals. Additionally, it discusses the paramagnetic properties of Methyl-O-Hairclip & S-Hairclip, the structure of tetramers, and the control over adsorption geometry and tautomerization. The lecture also addresses shot noise in STM, spin-polarization effects, and the manipulation of molecular magnetism through supramolecular interactions.
