One promising strategy is using unconventional spin\u2010orbit torque (SOT) exerted by the out\u2010of\u2010plane polarized spin current to enable deterministic magnetization switching and enhance the switching efficiency. However, in all\u2010vdW heterostructures, large unconventional SOT remains elusive and the robustness of the field\u2010free switching against external magnetic field has not been examined, which hinders further applications. Here, the study demonstrates the field\u2010free switching in an all\u2010vdW heterostructure combining a type\u2010II Weyl semimetal TaIrTe\n                    <jats:sub>4<\/jats:sub>\n                    and above\u2010room\u2010temperature ferromagnet Fe\n                    <jats:sub>3<\/jats:sub>\n                    GaTe\n                    <jats:sub>2<\/jats:sub>\n                    .

Moreover, it is found that the switching polarity cannot be changed until the external in\u2010plane magnetic field reaches 252\u00a0mT, indicating a robust switching against the magnetic field. The numerical simulation suggests the large unconventional SOT reduces the switching current density and enhances the robustness of the switching. The work shows that all\u2010vdW heterostructures are promising candidates for future highly efficient and stable SOT\u2010based devices.\n                  <\/jats:p>","DOI":"10.1002\/adma.202406464","type":"journal-article","created":{"date-parts":[[2024,8,14]],"date-time":"2024-08-14T09:10:05Z","timestamp":1723626605000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":46,"title":["Robust Field\u2010Free Switching Using Large Unconventional Spin\u2010Orbit Torque in an All\u2010Van der Waals Heterostructure"],"prefix":"10.1002","volume":"36","author":[{"given":"Yiyang","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Physics The Hong Kong University of Science and Technology  Kowloon Hong Kong SAR 999077 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolin","family":"Ren","sequence":"additional","affiliation":[{"name":"Department of Physics The Hong Kong University of Science and Technology  Kowloon Hong Kong SAR 999077 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruizi","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Electronic and Computer Engineering The Hong Kong University of Science and Technology  Kowloon Hong Kong SAR 999077 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zehan","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Physics The Hong Kong University of Science and Technology  Kowloon Hong Kong SAR 999077 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuezhao","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Electronic and Computer Engineering The Hong Kong University of Science and Technology  Kowloon Hong Kong SAR 999077 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Pang","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Condensed Matter Physics Institute of Physics Chinese Academy of Sciences  Beijing 100190 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Flexible Electronics (KLoFE) &amp; Institute of Advanced Materials (IAM) School of Flexible Electronics (Future Technologies) Nanjing Tech University (NanjingTech)  Nanjing 211816 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guibin","family":"Lan","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Condensed Matter Physics Institute of Physics Chinese Academy of Sciences  Beijing 100190 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Research Center for Electronic and Optical Materials National Institute for Materials Science  1\u20101 Namiki Tsukuba 305\u20100044 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takashi","family":"Taniguchi","sequence":"additional","affiliation":[{"name":"Research Center for Materials Nanoarchitectonics National Institute for Materials Science  1\u20101 Namiki Tsukuba 305\u20100044 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youguo","family":"Shi","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Condensed Matter Physics Institute of Physics Chinese Academy of Sciences  Beijing 100190 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guoqiang","family":"Yu","sequence":"additional","affiliation":[{"name":"Beijing National Laboratory for Condensed Matter Physics Institute of Physics Chinese Academy of Sciences  Beijing 100190 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2613-3031","authenticated-orcid":false,"given":"Qiming","family":"Shao","sequence":"additional","affiliation":[{"name":"Department of Physics The Hong Kong University of Science and Technology  Kowloon Hong Kong SAR 999077 China"},{"name":"Department of Electronic and Computer Engineering The Hong Kong University of Science and Technology  Kowloon Hong Kong SAR 999077 China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,8,14]]},"reference":[{"key":"e_1_2_9_1_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature22391"},{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature22060"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-018-0626-9"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41565-018-0121-3"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41565-018-0135-x"},{"key":"e_1_2_9_6_1","first-page":"28","volume":"6","author":"Tang M.","year":"2022","journal-title":"Nat.
