Depiction of the Molecule-Cobalt interface.
A trio if recent studies from our group in Nature Communications and Science Advances uncover how organic molecules can reshape and control magnetism in ultrathin cobalt.

In Science Advances, we reveal a hidden, highly anisotropic interfacial magnetic layer, universal across multiple molecule types, using ultrafast magneto-optical spectroscopy. In Nature Communications, we show how chemisorbed molecules induce a glassy magnetic state with colossal coercivity enhancement, and how resonant optical excitation of C₆₀ enables a transient 60% shift in cobalt’s ferromagnetic resonance frequency, paving the way for ultrafast, reversible control of proximity-enhanced magnetic properties.
