Semimetallic iridate compound SrIrO₃ epitaxial films have been deposited by off-axis sputtering, exhibiting excellent crystalline quality as well as smooth surfaces. By performing second-harmonic Hall measurements on a series of SrIrO₃/Co_1-xTb_x bilayers, we quantitatively determined the spin-to-charge interconversion efficiency θ_SH of SrIrO₃, and discovered a systematic temperature and film thickness dependent evolution behavior. Notably, the measured |θ_SH| reaches a remarkably large number of ~-1.1 at room temperature, which is significantly larger than the value of 5d transition metals and comparable to the values reported in some topological material systems. Finally, our findings are further corroborated by ferromagnetic resonance-driven spin pumping study in SrIrO₃/Py bilayers, highlighting the significant opportunities offered by the iridate compounds in designing next-generation energy-efficient multifunctional spin Hall devices.
