Investigated magnetic anisotropy and molecular orientation of iron phthalocyanine thin films on graphene, indicating significant changes.
We investigated the ground state, molecular orientation, and spin orientation of iron phthalocyanine (FePc) thin films grown on a monolayer graphene sheet by using X-ray absorption spectroscopy and X-ray magnetic circular dichroism. The X-ray absorption near-edge structure revealed that the molecular orientation of FePc on the graphene sheet was roughly flat-lying, whereas its orientation on silicon oxide was relatively perpendicular. Magnetic anisotropy was found to be significantly altered due to a change in the molecular orientation.
