Dynamics of proximity-induced magnetism at cobalt/molecular interfaces.

ABSTRACT: Interfacing ferromagnetic metals with organic molecules is a versatile strategy to control key parameters in magnetic and spintronic technologies. Hybridization between the metal's surface d orbitals and molecular p orbitals profoundly alters both the interfacial molecular layer and adjacent metal interface atomic layers, causing substantial changes in the magnetic properties of metal/molecule heterostructures. While magnetic modifications within the metallic layer are relatively well understood, the interfacial magnetism remains elusive. Using ultrafast time-resolved magneto-optical spectroscopy, we investigate the magnetic dynamics in such heterostructures and identify a distinct interfacial magnetic component that appears universal across various cobalt/molecule combinations.
