Abstract

The utilization of graphene on silicon carbide (SiC) substrates holds substantial promise for advancements in spintronics and nanoelectronics. Furthermore, incorporating magnetic metals provides an optimal framework for probing fundamental physical phenomena. Our approach to developing such systems is in situ intercalation of graphene with magnetic metals. In this study, we analyze the electronic structure and magnetic properties of the system synthesized by thermal decomposition of 6H‐SiC(0001) surface and subsequent intercalation of graphene with cobalt (Co) and iron (Fe) atoms. We employed X‐ray photoemission spectroscopy and low‐energy electron diffraction to control the synthesis and metal intercalation processes. The morphological characteristics of the synthesized system were studied by means of atomic force microscopy. Our findings derived from magneto‐optic Kerr effect measurements reveal a homogeneous ferromagnetic ordering at room temperature. Angle‐resolved photoemission spectroscopy was used to ascertain the impact of intercalation in graphene’s electronic structure. The results of this study are essential for development of graphene‐based spintronics and nanoelectronic devices as well as for fundamental studies in magnetic graphene systems.
