However, their use for spintronic applications remains elusive. Here, it is demonstrated that iridium based HEAs, grown by magnetron sputtering at room temperature, can be used as spin Hall layers. These films display highly efficient conversion of charge current into spin current. They also allow for the epitaxial growth of magnetic multilayers with perpendicular magnetic anisotropy as well as synthetic antiferromagnets using a ternary RuAlGa antiferromagnetic coupling layer. It is demonstrated that iridium\u2010based HEAs serve as effective sources of spin\u2010orbit torque, as quantified by spin\u2010torque ferromagnetic resonance and harmonic Hall measurements, enabling current\u2010induced magnetization reversal and domain wall motion. The threshold current density for current\u2010induced magnetization switching is found to be as low as \u223c10 MA cm<jats:sup>\u22122<\/jats:sup> with reproducible deterministic switching, and that domain walls in HEA\u2010based racetracks can be driven at speeds of up to 300 m s<jats:sup>\u22121<\/jats:sup> at a current density of 65 MA cm<jats:sup>\u22122<\/jats:sup>. These results show that HEAs should be considered for high\u2010performance spintronic applications.<\/jats:p>","DOI":"10.1002\/adma.202416820","type":"journal-article","created":{"date-parts":[[2025,6,5]],"date-time":"2025-06-05T01:40:16Z","timestamp":1749087616000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["High Entropy Alloy Thin Films as Efficient Spin\u2010Orbit Torque Sources for Spintronic Memories"],"prefix":"10.1002","volume":"37","author":[{"given":"Peng","family":"Wang","sequence":"first","affiliation":[{"name":"Max Planck Institute of Microstructure Physics  06120 Halle (Saale) Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6904-3573","authenticated-orcid":false,"given":"Andrea","family":"Migliorini","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics  06120 Halle (Saale) Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yung\u2010Cheng","family":"Li","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics  06120 Halle (Saale) Germany"},{"name":"Institute of Physics Martin Luther University Halle\u2010Wittenberg  06120 Halle (Saale) Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hakan","family":"Deniz","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics  06120 Halle (Saale) Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilya","family":"Kostanovski","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics  06120 Halle (Saale) Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae\u2010Chun","family":"Jeon","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics  06120 Halle (Saale) Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4702-6139","authenticated-orcid":false,"given":"Stuart S.
