The SOT efficiency first increases with increasing capping layer thickness (\n                    <jats:italic>d<\/jats:italic>\n                    <jats:sub>Ta<\/jats:sub>\n                    )\n                    <jats:italic>, reaching a large value of 0.199 at d<\/jats:italic>\n                    <jats:sub>Ta<\/jats:sub>\n                    = 1.4 nm, then decreases with further increases in\n                    <jats:italic>d<\/jats:italic>\n                    <jats:sub>Ta<\/jats:sub>\n                    . This can be attributed to a competition between the additional SOT field generated by the Rashba\u2013Edelstein effect and the reduced net spin current effect. It has been demonstrated that the magnetic damping factor decreases with increasing capping layer thickness. The high SOT efficiency and low magnetic damping factor suggest the great potential of the Ta\/Pt\/Co for low-power spintronic technologies.\n                  <\/jats:p>","DOI":"10.1088\/1361-648x\/ae1d04","type":"journal-article","created":{"date-parts":[[2025,11,7]],"date-time":"2025-11-07T22:52:12Z","timestamp":1762555932000},"page":"475801","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Large enhancement of effective spin\u2013orbit torque efficiency by optimizing the capping layer thickness in Ta\/Pt\/Co trilayer"],"prefix":"10.1088","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1224-9789","authenticated-orcid":true,"given":"Zhan","family":"Xu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4112-737X","authenticated-orcid":true,"given":"Shuo","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-2181-7692","authenticated-orcid":true,"given":"Runtian","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-6962-3183","authenticated-orcid":true,"given":"Wenwen","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9534-7469","authenticated-orcid":true,"given":"Er","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8248-586X","authenticated-orcid":true,"given":"Leixiang","family":"Bian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5802-7925","authenticated-orcid":true,"given":"Feng","family":"Xu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiaxuan","family":"Tang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5161-741X","authenticated-orcid":false,"given":"Wen Siang","family":"Lew","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2025,11,18]]},"reference":[{"key":"cmae1d04bib1","doi-asserted-by":"publisher","first-page":"56","DOI":"10.1038\/s44306-024-00054-z","type":"journal-article","article-title":"Recent progress on controlling spin-orbit torques by materials design","volume":"2","author":"Ji","year":"2024","journal-title":"npj Spintronics"},{"key":"cmae1d04bib2","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1109\/TMAG.2021.3078583","type":"journal-article","article-title":"Roadmap of spin\u2013orbit torques","volume":"57","author":"Shao","year":"2021","journal-title":"IEEE Trans.
