Synthesis and Properties of Monolayer Graphene (MLG)-Covered Fe(111)

Fe undergoes a corrosion process under aerobic conditions. Oxidized forms of Fe lose malleability, durability, and other critical physical properties. For spintronic applications, alloy forms or capping layers are used to modulate the properties of Fe. Observing the Fe(111) spin structure is critical for practical applications. We suggest a method of coating Fe to retain its original magnetic properties. Thanks to monolayer graphene (MLG) growth, the properties of the Fe spin structure do not change, even under ambient conditions. Through angle-resolved photoemission spectroscopy (ARPES) and low-energy electron diffraction (LEED) measurements, we also found that interfacial band structures are modulated due to the presence of MLG.
