Due to the cooperative effects of these interactions, the ferro-orbital order with different occupations of dyz and xdzx orbitals occurs and induces the tetragonal-orthorhombic structural transition at Ts, together with the stripe-type antiferromagnetic (AFM) order below TNTN. For a large gg case, we obtain the phase diagram consistent with the doped iron pnictides with Ts>TN for x>0, where the s++-wave superconductivity is mediated by the ferro-orbital fluctuation which is largely enhanced near the ferro-orbital QCP at Xc with Ts→0. On the other hand, for a small g case, the simultaneous phase transition occurs at Ts=TN even for x>0, where the s±-wave superconductivity is mediated by the AFM fluctuation. Both the s-wave states with full superconducting gaps are consistent with most of the experiments but only the former is considered to account for the small Tc-suppression against nonmagnetic impurities.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1016/j.ssc.2012.01.017","subitem_relation_type_select":"DOI"}}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00844573","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00381098","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ono, Yoshiaki"}],"nameIdentifiers":[{"nameIdentifier":"62","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yanagi, Yuki"}],"nameIdentifiers":[{"nameIdentifier":"38054","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Adachi, Naoko"}],"nameIdentifiers":[{"nameIdentifier":"38055","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamakawa, Youichi"}],"nameIdentifiers":[{"nameIdentifier":"38056","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-29"}],"displaytype":"detail","filename":"975.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"975.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2598/files/975.pdf"},"version_id":"d6c58212-9865-48a1-a551-2be180060842"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"A.
