Description

The magnetic dead layer for the ferromagnetic film on the semiconductor substrate is the concern issue for the magnetic device applications. In this study, we report the magnetic dead layer at the interfaces between Fe/graphene and Fe/HOPG surfaces. The Graphene was prepared at 1250 K on the SiC(0001) template. By using the magneto-optic Kerr effect, we found that at room temperature the ferromagnetic order appears at 3.3 ML and 5.5 ML for Fe/graphene and Fe/HOPG surface, respectively. From the thickness dependent magnetization measurements, we determined the magnetic dead layer for Fe/graphene and Fe/HOPG to be 2.5 ML and 5 ML, respectively.
