Spintronics field is one typical research field which is active both in scientific research and industrial application. The detection and manipulation of the spin freedom of the electrons becomes the central task of spintronics. Among all the techniques, optical techniques are very important by showing the accuracy and non-destructive property. The basic idea of the optic techniques in spintronics is the angular transfer between the electrons and photons. The spin-photon interface is also important in the study of quantum computation. This dissertation investigates three different spintronics systems with two different optic techniques (Sagnac magnetoptics and CPGE(circular photo galvanic effect)) revealing the photo-induced spin-accumulation at the FM/chiral HOIP interface, local Rashba states on the surface of the MAPbBr3 single crystal, SOT-induced magnetization change on the NiFe layer. The first chapter of the thesis is an general introduction to the spintronics field talking about related knowledge and theory as the basis of the thesis. It talks about the history of the spintronics, how the pure spin current is generated in spintroincs, the theory frame work for magnetooptics, SOT, CISS and CPGE. This chapter also simply introduces the properties of the hybrid perovskite studied in the dissertation. Second chapter describes how the experimental set-up is built up and run to conduct the research. It details the design and set-up of the sagnac moke system based on what reader can build a same experimental set-up as they want. It also describes the experimental set-up of the CPGE. The synthesis and fabrication process of studied devices are also mentioned in the chapter. Third chapter includes two parts: first part is an introduction to a new subfield ins spintronics which is also a main part of this thesis: Hybrid spintronics. Second part is a published manuscript shows the application of Saganc magetoptics in CISS effect. A new kind of CISS effect platform: Chiral hybrid perovskite is introduced in this manuscript. A photo-induced spin accumulation is observed through Sagnac MOKE. According to the CISS theory, the spin accumulation is controlled by either the chirality of the hybrid perovskite or the external magnetic field. Forth chapter shows another manuscript exhibits observed CPGE on the surface of theMAPbBr3 . Combination of CPGE, photo-ISHE and SHG techniques verifies the existence of local Rashba state on the surface of the MAPbBr3 . A DFT theory reveals that the physics origin of the local surface Rashba states could be the different terminals on the surface of the MAPbBr3 . Different terminals on the surface of the hybrid perovskite could lead to a big difference in Rashba coupling coefficient revealed by the magnitude of the CPGE effect. Fifth chapter comes back to the classical FM spintronics showing the application of Sagnac MOKE in SOT field. The change of the magnetization within FM layer due to the spin current generated in adjacent Pt layer is detected through Sagnac magnetooptics. Moreover, a hystersis of the switching of the FM layer and an in-plane angular dependence of the change of the kerr angle are detected.
