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\u003eTN for x\u003e0, 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\u003e0, 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", "download_preview_message": "", "file_order": 0, "filename": "975.pdf", "filesize": [{"value": "1.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1000000.0, "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.
