摘要:In my talk I will briefly introduce the spin Hall effect in 3D materials and the Edelstein effect in 2D systems [1]. I will show examples of the quantification of the efficiency of spin-to-charge current conversion in both phenomena using spin pumping -ferromagnetic resonance. In particular I will show the large efficiency measured using 2D systems such a Rashba interfaces, Ag/Bi [2] and SrTiO3/LaAlO3 [3], and topological insulators such as alpha-Sn [1]. On the other hand some examples of potentials applications using the spin-orbit torque switching [4] will be discussed.
