Spin-related interactions such as spin-orbit interaction (SOI) and Zeeman interaction are of crucial for fundamental and application aspects in spintronics so far. Especially SOI is very important in spintronics for generating, detecting, and manipulating spins solely by electrical means. Thus the pursuit for the spin-related interaction is required to realize further spin manipulation for future spintronics.
It is expected to control the spin Hall effect (SHE) through the coupling caused by the RKKY interaction between the spins and the magnetization.
We experimentally studied the coupling in Pt/Ru/Co system using the spin-torque ferromagnetic resonance technique. In this meeting, we report the Ru thickness dependence for making sure of the Friedel oscillation and the detailed mechanism in this system.
