powdered samples of hydrogen-doped tetragonal YBa_2Cu_3O_\u003c6+x\u003eH_y from 4.2 to 300 K.Four samples with different concentration types of oxygen and hydrogen atoms (x, y), which are (0.07,0.118), , (0.1,0.14), (0.11,0.078), and (0.17,0.01), were used. The line width of ^1H NMR increases abruptly below 20 K.The enhancements of T_2^\u003c-1\u003e and T_1^\u003c-1\u003e of ^\u003c63\u003eCu (1) NQR occur around 20 and 40 K,respectively. The relaxation mechanism of T_1 of ^\u003c63\u003eCu (1) NQR changes at T_m=about 80 K and the time dependence of its magnetization recovery shows a nonexponential type for T \u003c T_m and an exponential one for T \u003e T_m. The predominant origin for T_1 below T_m is found to be the fluctuating magnetic fields due to the staggered Cu^\u003c2+\u003e moments on the Cu (1) or Cu (2) site induced by the hole doping effect. Above T_m, T_1^\u003c-1\u003e of ^\u003c63\u003eCu (1) NQR increases gradually with temperature but it is almost temperature independent above 150 K,what can not be explained by the effect of the ordered AF Cu^\u003c2+\u003e moments in the Cu (2) O_2 plane and also by the Raman process of the lattice vibrations.", "subitem_description_type": "Other"}, {"subitem_description": "\u672a\u516c\u958b\uff1aP.4\u4ee5\u964d\uff08\u629c\u5237\u8ad6\u6587\u306e\u305f\u3081\uff09", "subitem_description_type": "Other"}, {"subitem_description": "\u7814\u7a76\u5831\u544a\u66f8", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u4e8c\u6728\u6cbb\u96c4"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/12027"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "NCID", "subitem_1522646572813": "BA35481350"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "research report", "resourceuri": "http://purl.org/coar/resource_type/c_18ws"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "07640486.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2004828/files/07640486.pdf"}, "version_id": "99bde9b4-01a7-478a-b558-d4cdf3a6cfce"}]}, "item_title": "\u9178\u5316\u7269\u9ad8\u6e29\u8d85\u4f1d\u5c0e\u4f53\u306b\u304a\u3051\u308b\u78c1\u6c17\u79e9\u5e8f\u306eNMR\u306b\u3088\u308b\u7814\u7a76", "item_type_id": "15", "owner": "1", "path": ["1642838403123", "1642838406414"], "permalink_uri": "http://hdl.handle.net/20.500.12000/12027", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-08-25"}, "publish_date": "2009-08-25", "publish_status": "0", "recid": "2004828", "relation": {}, "relation_version_is_last": true, "title": ["\u9178\u5316\u7269\u9ad8\u6e29\u8d85\u4f1d\u5c0e\u4f53\u306b\u304a\u3051\u308b\u78c1\u6c17\u79e9\u5e8f\u306eNMR\u306b\u3088\u308b\u7814\u7a76"], "weko_shared_id": -1}
