Atomically thin layered magnetic materials (LMMs) constitute an ideal platform to study magnetism in reduced dimensions.

One of the key features that distinguish LMMs from conventional bulk magnetic compounds is the tunability of their magnetic properties, which stems from their reduced dimensionality and the extremely high surface-to-volume ratio.

So far, the magnetic response of LMMs has been significantly altered only by using conventional approaches such as electrostatic gating.

Molecular functionalization, which is an extremely powerful method to tune the optoelectronic properties of non-magnetic 2D materials and to modify the magnetism of conventional metallic surfaces, has not yet been explored on LMMs..
