The magnetar 4U 0142+61, one of the prototypes of this class, was studied in broadband x rays (0.5\u201370 keV) with the Suzaku observatory. In hard x rays (15\u201340 keV), its 8.69 sec pulsations suffered slow phase modulations by \u00b10.7\u2009\u2009sec, with a period of \u223c15\u2009\u2009h. When this effect is interpreted as free precession of the neutron star, the object is inferred to deviate from spherical symmetry by \u223c1.6\u00d710^\u22124 in its moments of inertia. This deformation, when ascribed to magnetic pressure, suggests a strong toroidal magnetic field, \u223c10^12\u2009\u2009T, residing inside the object. This provides one of the first observational approaches towards toroidal magnetic fields of magnetars.", "subitem_description_type": "Abstract"}]}, "item_2_description_6": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "UTokyo Research\u63b2\u8f09\u300c\u5b87\u5b99\u3067\u6700\u5f37\u306a\u78c1\u77f3\u5929\u4f53\u304c\u3001\u78c1\u529b\u3067\u308f\u305a\u304b\u306b\u5909\u5f62\u3057\u3066\u3044\u308b\u5146\u5019\u3092\u767a\u898b\u300d URI: http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/the-strongest-magnetic-stars-are-possibly-deformed/", "subitem_description_type": "Other"}, {"subitem_description": "UTokyo Research \"The strongest magnetic stars are possibly deformed\" URI: http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/the-strongest-magnetic-stars-are-possibly-deformed/", "subitem_description_type": "Other"}]}, "item_2_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society"}]}, "item_2_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1103/Phys RevLett.112.171 102", "subitem_relation_type_select": "DOI"}}]}, "item_2_relation_25": {"attribute_name": "\u95a2\u4fc2URI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.u-tokyo.ac.jp/ja/utokyo-research/research-news/the-strongest-magnetic-stars-are-possibly-deformed/", "subitem_relation_type_select": "URI"}}, {"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.u-tokyo.ac.jp/en/utokyo-research/research-news/the-strongest-magnetic-stars-are-possibly-deformed/", "subitem_relation_type_select": "URI"}}, {"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.112.171102", "subitem_relation_type_select": "URI"}}]}, "item_2_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "(c) 2014 American Physical Society"}]}, "item_2_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00773679", "subitem_source_identifier_type": "NCID"}]}, "item_2_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0031-9007", "subitem_source_identifier_type": "ISSN"}, {"subitem_source_identifier": "1079-7114", "subitem_source_identifier_type": "ISSN"}]}, "item_2_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Journal Article"}]}, "item_2_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "Department of Physics, Graduate School of Science, the University of Tokyo"}, {"subitem_text_value": "Research Center for the Early Universe, Graduate School of Science, the University of Tokyo"}, {"subitem_text_value": "MAXI team, RIKEN"}, {"subitem_text_value": "High Energy Astrophysics Laboratory, RIKEN Nishina Center"}, {"subitem_text_value": "NASA Goddard Space Flight Center, Astrophysics Science Division"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Makishima, K."}], "nameIdentifiers": [{"nameIdentifier": "2204", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Enoto, T."}], "nameIdentifiers": [{"nameIdentifier": "2205", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hiraga, J.
