摘　　要：The hybrid organic–inorganic perovskites(HOIPs)have attracted much attention for their potential applications as novel optoelectronic devices.Remarkably,the Rashba band splitting,together with specific spin orientations in k-space(i.e.,spin texture),has been found to be relevant for the optoelectronic performances.In this work,by using first-principles calculations and symmetry analysis,we study the electric polarization,magnetism.
