Although ordered magnetic phases have been demonstrated to survive in the two-dimensional (2D) limit, the quest for a spin glass with quenched magnetic disorder in lower dimensions has proven elusive. Here, we provide evidence of a spin glass emerging from randomly distributed Fe atoms in Fe\n                    <jats:sub>3<\/jats:sub>\n                    GeTe\n                    <jats:sub>2<\/jats:sub>\n                    (FGT). ac magnetic susceptibility displays a strong frequency dependence indicative of slow spin dynamics. Additional distinctive phenomena, including aging, chaos, and memory effects, further substantiate the existence of a glassy state. Notably, we found that this state persists even in single-cell\u2013thick FGT, thereby confirming the existence of a 2D spin glass.\n                  <\/jats:p>","DOI":"10.1126\/science.adp0091","type":"journal-article","created":{"date-parts":[[2026,5,7]],"date-time":"2026-05-07T18:00:48Z","timestamp":1778176848000},"page":"624-628","update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":5,"title":["Realization of a spin glass in a two-dimensional van der Waals material"],"prefix":"10.1126","volume":"392","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2423-4373","authenticated-orcid":true,"given":"Banabir","family":"Pal","sequence":"first","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4872-1638","authenticated-orcid":true,"given":"Ajesh","family":"Kollakuzhiyil Gopi","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1617-6695","authenticated-orcid":true,"given":"Yicheng","family":"Guan","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6156-8623","authenticated-orcid":true,"given":"Ruifeng","family":"Wang","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anirban","family":"Chakraborty","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kajal","family":"Tiwari","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-3051-6617","authenticated-orcid":true,"given":"Anagha","family":"Mathew","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9875-4438","authenticated-orcid":true,"given":"Abhay K.","family":"Srivastava","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenjie","family":"Zhang","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-4551-1719","authenticated-orcid":true,"given":"Ilya","family":"Kostanovski","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7284-7396","authenticated-orcid":true,"given":"Binoy K.","family":"Hazra","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1448-4793","authenticated-orcid":true,"given":"Holger","family":"Meyerheim","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4702-6139","authenticated-orcid":true,"given":"Stuart S.
