However, in traditional ferromagnetic\/nonmagnetic heterojunctions, the interfacial Rashba spin-orbit coupling brings about spin memory loss (SML) and two-magnon scattering (TMS), quenching spin current crossing the heterointerfaces. To address the intrinsic deficiency of heterointerface, we design a ferromagnetic FeRh\/antiferromagnetic FeRh spin homojunction for efficient spin-charge conversion, verified by a high interfacial transparency of 0.75 and a high spin torque efficiency of 0.34 from spin pumping measurements. First-principles calculations demonstrate that the interfacial electric field of homojunction is two orders of magnitude smaller than that of traditional heterojunction, producing negligible interfacial spin-orbit coupling to drastically reduce SML and TMS. Our spin homojunction exhibits potential and enlightenment for future energy-efficient spintronic devices.<\/jats:p>","DOI":"10.1126\/sciadv.abq2742","type":"journal-article","created":{"date-parts":[[2022,9,21]],"date-time":"2022-09-21T17:58:34Z","timestamp":1663783114000},"source":"Crossref","is-referenced-by-count":19,"title":["Spin homojunction with high interfacial transparency for efficient spin-charge conversion"],"prefix":"10.1126","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6152-0307","authenticated-orcid":true,"given":"Lei","family":"Han","sequence":"first","affiliation":[{"name":"Key Laboratory of Advanced Materials (MOE), School of Materials Science and Engineering, Tsinghua University, Beijing 100084, P.
