| contents | Functional oxides and hybrid structures with interfacial spin orbit coupling and the Rashba-Edelsterin effect (REE) are promising materials systems for thermal tolerance spintronic device applications. Here, we demonstrate efficient spin-to-charge conversion through enhanced interfacial spin orbit coupling at the all-oxide interface of La1-xCaxMnO3 with quasi-two-dimensional (quasi-2D) SrTiO3 (LCMO/STO). The quasi-2D interface is generated via oxygen vacancies at the STO surface. We obtain a spin-to-charge conversion efficiency of ~ 2.32 +- 1.3 nm, most likely originating from the inverse REE, which is relatively large versus all-metallic spin-to-charge conversion materials systems. The results highlight that the LCMO/STO 2D electron gas is a potential platform for spin-based memory and transistor applications. |
