Spin-charge conversion via spin-orbit interaction is one of the core conceptsin the current spintronics research. The efficiency of the interconversionbetween charge and spin current is estimated based on Berry curvature of Blochwavefunction in the linear-response regime. Beyond the linear regime, nonlinearspin-charge conversion in the higher-order electric field terms has recentlybeen demonstrated in noncentrosymmetric materials with nontrivial spin texturein the momentum space. Here we report the observation of the nonlinearcharge-spin conversion in a nominally centrosymmetric oxide material, SrIrO3,by breaking inversion symmetry at the interface. A large second-ordermagnetoelectric coefficient is observed at room temperature because of theantisymmetric spin-orbit interaction at the interface of Dirac semimetallicbands, which is subject to the symmetry constraint of the substrates. Our studysuggests that nonlinear spin-charge conversion can be induced in many materialswith strong spin-orbit interaction at the interface by breaking the localinversion symmetry to give rise to spin splitting in otherwise spin degeneratesystems.
