By using a BEDT-TTF molecule with $^{13}\\mathrm{C}$ as one of its central carbons, we could estimate the density of states from the Knight shift and the spin-lattice relaxation rate. Although the reduced mass effect predicted from the specific-heat measurement was not observed in the $^{13}\\mathrm{C}$-NMR spectrum, a metal-to-antiferromagnetic phase transition was observed with a phase separation at around $18\\phantom{\\rule{0.3em}{0ex}}\\mathrm{K}$ on the half-deuterated $\\ensuremath{\\kappa}\\text{\\ensuremath{-}}{(\\mathrm{BEDT}\\text{\\ensuremath{-}}\\mathrm{TTF})}_{2}\\mathrm{Cu}[\\mathrm{N}{(\\mathrm{C}\\mathrm{N})}_{2}]\\mathrm{Br}$ under a high magnetic field. No such transition occurred in the half-deuterated salt under a zero or low field. These results point to a first-order field-induced metal-insulator transition. These findings can explain the complex phenomena observed near the phase boundary under a high magnetic field."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382262946443351681","@type":"Researcher","foaf:name":[{"@value":"Atsushi Kawamoto"}]},{"@id":"https://cir.nii.ac.jp/crid/1382262946443351680","@type":"Researcher","foaf:name":[{"@value":"Masato Yamasita"}]},{"@id":"https://cir.nii.ac.jp/crid/1382262946443351682","@type":"Researcher","foaf:name":[{"@value":"Ken-ichi Kumagai"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"10980121"},{"@type":"EISSN","@value":"1550235X"}],"prism:publicationName":[{"@value":"Physical Review B"}],"dc:publisher":[{"@value":"American Physical Society (APS)"}],"prism:publicationDate":"2004-12-17","prism:volume":"70","prism:number":"21","prism:startingPage":"212506"},"reviewed":"false","dc:rights":["http://link.aps.org/licenses/aps-default-license"],"url":[{"@id":"http://link.aps.org/article/10.1103/PhysRevB.70.212506"},{"@id":"http://harvest.aps.org/v2/journals/articles/10.1103/PhysRevB.70.212506/fulltext"}],"createdAt":"2004-12-17","modifiedAt":"2019-01-02","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050292859826559872","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"Antiferromagnetic ordering of organic Mott insulator λ-(BEDSe-TTF)2GaCl4"},{"@value":"Antiferromagnetic ordering of organic Mott insulator \n<mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\"><mml:mi>λ</mml:mi><mml:mtext>−</mml:mtext><mml:msub><mml:mrow><mml:mo>(</mml:mo><mml:mtext>BEDSe-TTF</mml:mtext><mml:mo>)</mml:mo></mml:mrow><mml:mn>2</mml:mn></mml:msub><mml:msub><mml:mi mathvariant=\"normal\">GaCl</mml:mi><mml:mn>4</mml:mn></mml:msub></mml:math>"}]},{"@id":"https://cir.nii.ac.jp/crid/1360284921847608320","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Effect of X-ray Irradiation on the Organic Superconductor κ-(BEDT-TTF)<sub>2</sub>Cu(NCS)<sub>2</sub>Probed by<sup>13</sup>C-NMR"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679173374592","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"<SUP>13</SUP>C-NMR Study of Charge Ordering State in the Organic Conductor, α-(BEDT-TTF)<SUB>2</SUB>I<SUB>3</SUB>"},{"@value":"13C-NMR study of charge ordering state in the organic conductor, α-(BEDT-TTF)2I3"},{"@language":"ja-Kana","@value":"13C NMR study of charge ordering state in the organic conductor a BEDT TTF 2I3"}]},{"@id":"https://cir.nii.ac.jp/crid/2051714792013601536","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Antiferromagnetic ground state of molecular π-d system λ-(BEDT-STF)2FeCl4 studied by site-selective magnetization and thermodynamic measurements"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1103/physrevb.70.212506"},{"@type":"OPENAIRE","@value":"doi_dedup___::9815c4228dceed1e58a7687b042f9fa0"},{"@type":"CROSSREF","@value":"10.1143/jpsj.78.074711_references_DOI_TfGn7sah0RLKaJDFiQi37ZCw9ZZ"},{"@type":"CROSSREF","@value":"10.1246/cl.210767_references_DOI_TfGn7sah0RLKaJDFiQi37ZCw9ZZ"},{"@type":"CROSSREF","@value":"10.1103/physrevb.106.045114_references_DOI_TfGn7sah0RLKaJDFiQi37ZCw9ZZ"},{"@type":"CROSSREF","@value":"10.1143/jpsj.81.114709_references_DOI_TfGn7sah0RLKaJDFiQi37ZCw9ZZ"}]}
