Whereas the magnetism of monolayers of chromium iodide (CrI\n                    <jats:sub>3<\/jats:sub>\n                    ) can be understood in terms of out-of-plane magnetic anisotropy, the related material chromium chloride (CrCl\n                    <jats:sub>3<\/jats:sub>\n                    ) has spins that lie in the plane. Bedoya-Pinto\n                    <jats:italic>et al<\/jats:italic>\n                    . used molecular beam epitaxy to grow monolayers of CrCl\n                    <jats:sub>3<\/jats:sub>\n                    on graphene and studied its magnetic properties. Using x-ray magnetic circular dichroism measurements, the authors found that monolayer CrCl\n                    <jats:sub>3<\/jats:sub>\n                    is a ferromagnet, unlike bulk CrCl\n                    <jats:sub>3<\/jats:sub>\n                    , which is antiferromagnetic. The scaling of the signal in the critical region indicated that the material belongs to the 2D-XY universality class, distinct from Ising magnetism, which some other 2D magnets exhibit. \u2014JS\n                  <\/jats:p>","DOI":"10.1126\/science.abd5146","type":"journal-article","created":{"date-parts":[[2021,10,28]],"date-time":"2021-10-28T14:01:59Z","timestamp":1635429719000},"page":"616-620","source":"Crossref","is-referenced-by-count":262,"title":["Intrinsic 2D-XY ferromagnetism in a van der Waals monolayer"],"prefix":"10.1126","volume":"374","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5449-3179","authenticated-orcid":true,"given":"Amilcar","family":"Bedoya-Pinto","sequence":"first","affiliation":[{"name":"NISE Department, Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2398-712X","authenticated-orcid":true,"given":"Jing-Rong","family":"Ji","sequence":"additional","affiliation":[{"name":"NISE Department, Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7160-5934","authenticated-orcid":true,"given":"Avanindra K.","family":"Pandeya","sequence":"additional","affiliation":[{"name":"NISE Department, Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6649-0538","authenticated-orcid":true,"given":"Pierluigi","family":"Gargiani","sequence":"additional","affiliation":[{"name":"ALBA Synchrotron Light Source, Barcelona, Spain."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4895-8114","authenticated-orcid":true,"given":"Manuel","family":"Valvidares","sequence":"additional","affiliation":[{"name":"ALBA Synchrotron Light Source, Barcelona, Spain."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1261-0386","authenticated-orcid":true,"given":"Paolo","family":"Sessi","sequence":"additional","affiliation":[{"name":"NISE Department, Max Planck Institute of Microstructure Physics, Halle, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5274-8545","authenticated-orcid":true,"given":"James M.","family":"Taylor","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum f\u00fcr Materialien und Energie, Berlin, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0284-7937","authenticated-orcid":true,"given":"Florin","family":"Radu","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum f\u00fcr Materialien und Energie, Berlin, Germany."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4965-4537","authenticated-orcid":true,"given":"Kai","family":"Chang","sequence":"additional","affiliation":[{"name":"NISE Department, 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.
