The plateau's stabilization is accompanied by a significant increase of the magnetic unit cell, as the magnetic peaks with fractional indices are observed in single-crystal neutron diffraction experiments. At low temperatures, the inelastic neutron scattering measurements reveal the presence of low-energy, almost dispersionless excitations. Their spectrum is sensitive to the applied field, it significantly softens on the magnetization plateau, and demonstrates the behavior expected for a noncollinear Ising antiferromagnet away from the plateau.<\/jats:p>\n          <jats:sec>\n            <jats:title\/>\n            <jats:supplementary-material>\n              <jats:permissions>\n                <jats:copyright-statement>Published by the American Physical Society<\/jats:copyright-statement>\n                <jats:copyright-year>2024<\/jats:copyright-year>\n              <\/jats:permissions>\n            <\/jats:supplementary-material>\n          <\/jats:sec>","DOI":"10.1103\/physrevb.109.094420","type":"journal-article","created":{"date-parts":[[2024,3,14]],"date-time":"2024-03-14T14:59:41Z","timestamp":1710428381000},"update-policy":"https:\/\/doi.org\/10.1103\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Magnetic structure, excitations, and field-induced transitions in the honeycomb lattice compound \n<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\"><mml:mrow><mml:msub><mml:mi>Er<\/mml:mi><mml:mn>2<\/mml:mn><\/mml:msub><mml:msub><mml:mi>Si<\/mml:mi><mml:mn>2<\/mml:mn><\/mml:msub><mml:msub><mml:mi mathvariant=\"normal\">O<\/mml:mi><mml:mn>7<\/mml:mn><\/mml:msub><\/mml:mrow><\/mml:math>"],"prefix":"10.1103","volume":"109","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8759-614X","authenticated-orcid":true,"given":"M.","family":"Islam","sequence":"first","affiliation":[{"name":"Department of Physics, University of Warwick, Coventry CV4 7AL, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"d'Ambrumenil","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Warwick, Coventry CV4 7AL, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.
