For the compatibility with Bi2223 phase formation\nduring sintering, SrZrO3 was selected as barrier materials.\nMoreover, small amount of Bi2212 was mixed with SrZrO3 to\nimprove its ductility for cold working. Although some breakages\nof barrier layers still existed, the effective transverse resistivity\nwas approximately 10 times higher than a tape with pure Ag\nmatrix. By controlling barrier thickness, reducing a tape width\nbelow 3 mm and twisting the filaments with its length below 5 mm,\ncoupling frequency fc attained to 260 Hz in an AC perpendicular\ntransverse field. Critical current densities Jc of our twisted barrier\ntapes were ranged in 12−15 kA/cm2 at 77 K and self-field, which\nwas 25−30 % lower than non-twisted one (= 18 kA/cm2). In our\nknowledge, this is the first report to achieve both Jc \u003e 12 kA/cm2\nand fc \u003e 250 Hz simultaneously in a single Bi2223 tapes. Our\nbarrier tapes showed 60-70% lower perpendicular field losses\nthan a conventional 4 mm-width tape with fully coupled filaments\nat 50 mT and 50 Hz. These results are promising for remarkable\nimprovement in AC performance for Bi2223 tapes in future.", "subitem_description_type": "Abstract"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "IEEE"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1109/TASC.2010.2078433", "subitem_relation_type_select": "DOI"}}]}, "item_10001_relation_17": {"attribute_name": "関連サイト", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "IEEExplore"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=5617306", "subitem_relation_type_select": "URI"}}]}, "item_10001_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "This is the author\u0027s version of the work.
