However, modulating the interface's electronic structure to make it abnormally asymmetric has been challenging because of lack of appropriate methods. Here, the authors report that low\u2010energy proton irradiation achieves a strong level of inversion asymmetry and unusual strain at interfaces in [Co\/Pd] superlattices through nondestructive, selective removal of oxygen from Co<jats:sub>3<\/jats:sub>O<jats:sub>4<\/jats:sub>\/Pd superlattices during irradiation. Structural investigations corroborate that progressive reduction of Co<jats:sub>3<\/jats:sub>O<jats:sub>4<\/jats:sub> into Co establishes pseudomorphic growth with sharp interfaces and atypically large tensile stress. The normal component of orbital to spin magnetic moment at the interface is the largest among those observed in layered Co systems, which is associated with giant orbital anisotropy theoretically confirmed, and resulting very large interfacial magnetic anisotropy is observed. All results attribute not only to giant orbital anisotropy but to enhanced interfacial spin\u2013orbit coupling owing to the pseudomorphic nature at the interface. They are strongly supported by the observation of reversal of polarity of temperature\u2010dependent Anomalous Hall signal, a signature of Berry phase. This work suggests that establishing both giant orbital anisotropy and strong spin\u2013orbit coupling at the interface is key to exploring spintronic devices with new functionalities.<\/jats:p>","DOI":"10.1002\/advs.202201749","type":"journal-article","created":{"date-parts":[[2022,6,24]],"date-time":"2022-06-24T04:14:07Z","timestamp":1656044047000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Giant Orbital Anisotropy with Strong Spin\u2013Orbit Coupling Established at the Pseudomorphic Interface of the Co\/Pd Superlattice"],"prefix":"10.1002","volume":"9","author":[{"given":"Sanghoon","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering Yonsei University  Seoul 03722 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sachin","family":"Pathak","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Yonsei University  Seoul 03722 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sonny H.","family":"Rhim","sequence":"additional","affiliation":[{"name":"Department of Physics University of Ulsan  Ulsan 44610 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jongin","family":"Cha","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Yonsei University  Seoul 03722 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soyoung","family":"Jekal","sequence":"additional","affiliation":[{"name":"Department of Physics University of Ulsan  Ulsan 44610 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soon Cheol","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Physics University of Ulsan  Ulsan 44610 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyun Hwi","family":"Lee","sequence":"additional","affiliation":[{"name":"Pohang Acceleration Laboratory  Pohang 37673 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sung\u2010Hun","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Physics Pohang University of Science and Technology  Pohang 37673 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Han\u2010Koo","family":"Lee","sequence":"additional","affiliation":[{"name":"Pohang Acceleration Laboratory  Pohang 37673 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jae\u2010Hoon","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Physics Pohang University of Science and Technology  Pohang 37673 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soogil","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Yonsei University  Seoul 03722 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans\u2010Georg","family":"Steinr\u00fcck","sequence":"additional","affiliation":[{"name":"Department of Chemistry Paderborn University  Paderborn 33098 Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Apurva","family":"Mehta","sequence":"additional","affiliation":[{"name":"SSRL Materials Science Division SLAC National Accelerator Laboratory  CA 94025 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shan X.","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering and Electrical Engineering Stanford University  CA 94305 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3790-800X","authenticated-orcid":false,"given":"Jongill","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Yonsei University  Seoul 03722 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,6,24]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRev.100.580"},{"key":"e_1_2_8_2_1","first-page":"1109","volume":"2","author":"Rashba E.
