This phenomenon has garnered attention for its potential to enable energy\u2010efficient spintronic devices, such as SOT magnetic random\u2010access memory. In this study, a high\u2010quality RuO<jats:sub>2<\/jats:sub> (100) epitaxial film with a well\u2010controlled triple\u2010domain\u2010structure is analyzed, and it is confirmed that out\u2010of\u2010plane spin\u2010current generation is independent of the N\u00e9el vector (). This  independence of the out\u2010of\u2010plane spin current leads to equal SOT values for the two orthogonal currents. The spin\u2010split effect\u2010induced SOT demonstrates a field\u2010like (FL) torque efficiency (\u22120.066\u00a0\u00b1\u00a00.001) that is six times higher than that of the Slonczewski\u2010like torque efficiency (\u22120.011\u00a0\u00b1\u00a00.001). Furthermore, micromagnetic simulations show that this high FL torque reduces the critical switching voltage by a factor of 2.6 in the sub\u2010nanosecond regime in an SOT device. These findings contribute to advancing research and the development of highly energy\u2010efficient antiferromagnetic\u2010based SOT magnetic random\u2010access memory.<\/jats:p>","DOI":"10.1002\/advs.202413165","type":"journal-article","created":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T02:38:01Z","timestamp":1741747081000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Enhanced
