Large Tunable Spin-to-Charge Conversion in NiFe/Molybdenum Disulfide by Cu Insertion.

Spin-to-charge conversion at the interface between magnetic materials and transition metal dichalcogenides has drawn great interest in the research efforts to develop fast and ultralow power consumption devices for spintronic applications. Here, we report room temperature observations of spin-to-charge conversion arising from the interface of NiFe (Py) and molybdenum disulfide (MoS). This phenomenon can be characterized by the inverse Edelstein effect length (λ), which is enhanced with decreasing MoS thicknesses, demonstrating the dominant role of spin-orbital coupling (SOC) in MoS.
