Considering the full range of crystal field induced tetragonal splitting in a realistic three-orbital model, collective spin\u2013orbital excitations are investigated using the generalized self-consistent plus fluctuation approach. At ambient pressure, an entangled orbital + antiferromagnetic order is found to be stabilized beyond a critical value (\u223c30 meV) of spin\u2013orbit coupling which is in the realistic range for 3d ions. The behavior of the calculated energy scales of collective excitations with crystal field is consistent with that of the transition temperatures with pressure as obtained from susceptibility and resistivity anomalies in high-pressure studies.<\/jats:p>","DOI":"10.1088\/1361-648x\/aca63e","type":"journal-article","created":{"date-parts":[[2022,11,25]],"date-time":"2022-11-25T17:20:40Z","timestamp":1669396840000},"page":"045801","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Spin\u2013orbit coupling, orbitally entangled antiferromagnetic order, and collective spin\u2013orbital excitations in \n\t    \n\t    <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\">\n                     <mml:msub>\n                        <mml:mtext>Sr<\/mml:mtext>\n                        <mml:mtext>2<\/mml:mtext>\n                     <\/mml:msub>\n                     <mml:msub>\n                        <mml:mtext>VO<\/mml:mtext>\n                        <mml:mtext>4<\/mml:mtext>\n                     <\/mml:msub>\n                  <\/mml:math>"],"prefix":"10.1088","volume":"35","author":[{"given":"Shubhajyoti","family":"Mohapatra","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dheeraj","family":"Kumar Singh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajyavardhan","family":"Ray","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sayandip","family":"Ghosh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3161-641X","authenticated-orcid":true,"given":"Avinash","family":"Singh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2022,12,12]]},"reference":[{"key":"cmaca63ebib1","doi-asserted-by":"publisher","first-page":"321","DOI":"10.1016\/S0022-4596(05)80090-8","type":"journal-article","article-title":"Properties of a new perovskite oxide Sr2VO4","volume":"85","author":"Cyrot","year":"1990","journal-title":"J.
