Synthesis and Electrical Characterization of Magnetic Bilayer Graphene Intercalate

Abstract

We report synthesis and transport properties of the minimal graphite intercalation compound, a ferric chloride (FeCl3) island mono layer inside bilayer graphene. Chemical doping by the intercalant is simultaneously probed by micro Raman spectroscopy and Hall measurements. Quantum oscillations of conductivity originate from microscopic domains of intercalated and uninterealated regions. A slight upturn in resistance related to magnetic transition is observed Two-dimensional intercalation bilayer graphene opens new possibilities to engineer two dimensional Properties of intercalates.
