Here we show that systematic anion substitution in a family of rare-earth van der Waals (vdW) magnets, YbChX (Ch = S, Se; X = Br, I), provides a direct chemical handle on this boundary. By replacing chalcogenide and halide ligands on the FeOCl-type lattice, we systematically tune the crystal electric field hierarchy, the degree of XY anisotropy, and the strength of quantum fluctuations in the ground-state Kramers doublet, affecting the exchange interactions without changing the distorted triangular lattice topology. The result is a series of Jeff = 1\/2 magnets with large frustration factors (f = 9\u201376), extended short-range correlation regimes, and suppressed long-range order, placing the entire family in close proximity to magnetic quantum criticality. Far-infrared magnetospectroscopy, diffuse reflectance, and photoluminescence reveal that the same ligand substitution that reshapes the magnetic landscape simultaneously tunes f\u2013f optical transitions, opening a route to access potential spin\u2013photon coupling through chemical modifications. These results establish anion substitution as a powerful design principle for chemically navigating frustrated quantum magnets toward exotic ground states in the vdW family.<\/jats:p>","DOI":"10.1021\/jacs.6c12112","type":"journal-article","created":{"date-parts":[[2026,10,1]],"date-time":"2026-10-01T11:01:20Z","timestamp":1790852480000},"page":"43334-43343","source":"Crossref","is-referenced-by-count":0,"title":["Tunable Quantum Magnetism\nin Frustrated Yb-Based van\nder Waals Materials"],"prefix":"10.1021","volume":"148","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3445-0347","authenticated-orcid":true,"given":"Jiayi","family":"Li","sequence":"first","affiliation":[{"name":"Columbia University , , , ,","place":["New York, New York, United States, 10027"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1787-7058","authenticated-orcid":true,"given":"Arun","family":"Ramanathan","sequence":"additional","affiliation":[{"name":"Columbia University , , , ,","place":["New York, New York, United States, 10027"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8055-3710","authenticated-orcid":true,"given":"Thom J.","family":"Snoeren","sequence":"additional","affiliation":[{"name":"University of Washington , , , ,","place":["Seattle, Washington, United States, 98195"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2984-7611","authenticated-orcid":true,"given":"Willa","family":"Mihalyi-Koch","sequence":"additional","affiliation":[{"name":"Columbia University , , , ,","place":["New York, New York, United States, 10027"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jamie","family":"Cleron","sequence":"additional","affiliation":[{"name":"Stanford University , , , ,","place":["Stanford, California, United States, 94305"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Champ","sequence":"additional","affiliation":[{"name":"Columbia University , , , ,","place":["New York, New York, United States, 10027"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4949-8068","authenticated-orcid":true,"given":"Hemamala I.","family":"Karunadasa","sequence":"additional","affiliation":[{"name":"Stanford University , , , ,","place":["Stanford, California, United States, 94305"]},{"name":"SLAC National Accelerator Laboratory , , , ,","place":["Menlo Park, California, United States, 94025"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5470-1158","authenticated-orcid":true,"given":"Mykhaylo","family":"Ozerov","sequence":"additional","affiliation":[{"name":"National High Magnetic Field Laboratory , , ,","place":["Tallahassee, Florida, United States, 32310"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2888-9916","authenticated-orcid":true,"given":"Daniel R.","family":"Gamelin","sequence":"additional","affiliation":[{"name":"University of Washington , , , ,","place":["Seattle, Washington, United States, 98195"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allen","family":"Scheie","sequence":"additional","affiliation":[{"name":"Los Alamos National Laboratory , , , ,","place":["Los Alamos, New Mexico, United States, 87545"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8850-0725","authenticated-orcid":true,"given":"Xavier","family":"Roy","sequence":"additional","affiliation":[{"name":"Columbia University , , , ,","place":["New York, New York, United States, 10027"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,1]]},"reference":[{"key":"2026101414091526200_cit1","doi-asserted-by":"publisher","first-page":"453","DOI":"10.1146\/annurev.ms.24.080194.002321","article-title":"Strongly\nGeometrically Frustrated Magnets","volume":"24","author":"Ramirez","year":"1994","journal-title":"Annu.
