Spin-charge and orbit-charge conversion at Rashba interfaces

The proposed project aims to assess the spin-charge and orbit-charge conversion efficiency of various systems (oxide 2DEGs, Rashba interfaces, etc) using spin-pumping from ferromagnetic resonance (SP-FMR). The samples will be patterned to perform broadband FMR with coplanar waveguides and measure the transverse charge current produced at resonance. Systematic measurements, e.g. as a function of the magnetic field angle, will be performed and the data carefully analyzed to isolate the spin-charge and/or orbit-charge conversion signals and quantify the conversion efficiency. The objective will be to achieve large output signals at room temperature.
