The longitudinal- and transverse-acoustic (LA and TA) phonon frequencies deviate below the Burns temperature TB=736  K from a linear temperature dependence above TB, indicating the existence of polarization relaxations induced by the polar nanoregions (PNRs). On further cooling, a central peak (CP) which originates from the relaxations in the PNRs is observed clearly below 600  K\u003cTB. The CP width decreases markedly down to T*=499  K and the change in the CP width becomes mild below T*. The slower (~10\u221212  s) and faster (~10\u221213  s) relaxation times determined by the CP show good agreement with the relaxation times determined by TA and LA phonons, respectively. 180\u00b0 and non-180\u00b0 (71\u00b0 and 109\u00b0) polarization flippings are allowed in the PNRs with the polar rhombohedral symmetry. Considering the piezoelectric coupling in a PNR, it is suggested that 180\u00b0 flipping is related to the relaxation observed in LA phonon, while non-180\u00b0 flipping is related to that in TA phonon.", "subitem_description_type": "Abstract"}]}, "item_5_identifier_34": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2241/101217"}]}, "item_5_publisher_27": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "The American Physical Society"}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1103/PhysRevB.78.144106", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a92008 The American Physical Society"}]}, "item_5_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1098-0121", "subitem_source_identifier_type": "ISSN"}]}, "item_5_source_id_9": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA11187113", "subitem_source_identifier_type": "NCID"}]}, "item_5_subject_20": {"attribute_name": "NII\u30b5\u30d6\u30b8\u30a7\u30af\u30c8", "attribute_value_mlt": [{"subitem_subject": "\u57fa\u790e\u5de5\u5b66\u30fb\u5fdc\u7528\u7269\u7406\u5b66", "subitem_subject_scheme": "Other"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tsukada, Shinya"}], "nameIdentifiers": [{"nameIdentifier": "60700", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kojima, Seiji"}], "nameIdentifiers": [{"nameIdentifier": "60701", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2013-12-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "PRB_78-14.pdf", "filesize": [{"value": "484.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 484300.0, "url": {"label": "PRB_78-14.pdf", "url": "https://tsukuba.repo.nii.ac.jp/record/17051/files/PRB_78-14.pdf"}, "version_id": "5cf205b7-0430-441a-9640-349e28982050"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Broadband light scattering of two relaxation processes in relaxor ferroelectric 0.93Pb(Zn1/3Nb2/3)O3-0.07PbTiO3 single crystals", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Broadband light scattering of two relaxation processes in relaxor ferroelectric 0.93Pb(Zn1/3Nb2/3)O3-0.07PbTiO3 single crystals"}]}, "item_type_id": "5", "owner": "1", "path": ["117/148", "3/62/5598/82"], "permalink_uri": "http://hdl.handle.net/2241/101217", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2008-12-10"}, "publish_date": "2008-12-10", "publish_status": "0", "recid": "17051", "relation": {}, "relation_version_is_last": true, "title": ["Broadband light scattering of two relaxation processes in relaxor ferroelectric 0.93Pb(Zn1/3Nb2/3)O3-0.07PbTiO3 single crystals"], "weko_shared_id": 5}
