| Abstract |
Analysis of magnetic behavior of Fe deposited on MoS2 flakes was carried out by magneto-optic Kerr effect (MOKE). Small hysteresis loop was observed after depositing 12.5 Å of Fe on transferred MoS_2 ...flakes on clean SiO_2 substrate. Using thickness dependent study of Kerr rotation, it was found that magnetic dead layer (MDL) existed at the interface of Fe and MoS2 up to 7 Å of Fe deposition. The presence of magnetically dead layer was due to the existence of small interaction between Fe and MoS_2 which led to the generation of antiferromagnetic coupling between atoms at the interface. With the increase of Fe deposition, interactivity of Fe and MoS_2 was decreased and prompted magnetism through ferromagnetic coupling between deposited Fe atoms.show more
