| Abstract | Because of the unique properties of graphene, the combination of perpendicular magnetized materials and a carbon-based template is especially useful. This study examines the effect of highly oriented pyrolytic graphite (HOPG) surface defects on Fe thin films. Numerous Fe thin films were grown on planar HOPG (p-HOPG) and Arþ sputtered HOPG (s-HOPG), for comparison. X-ray diffraction showed the preferred (110) texture for Fe films on both p-HOPG and s-HOPG. Fe/p-HOPG exhibited only in-plane magnetization. In contrast, Fe/s-HOPG exhibited the coexistence of in-plane and perpendicular magneto-optical Kerr effect hysteresis loops, indicating a stable, canted magnetization. The canted magnetization of Fe/s-HOPG persisted to at least 20 atomic monolayers and might be attributed to a volume-contributed perpendicular anisotropy. These observations are relevant to a combination of ferromagnetic thin films and graphene-related templates. VC 2011 American Institute of Physics. [doi:10.1063/1.3654141] |
