After an applied magnetic field is switched off, the time decay of Hall resistivity (or remanent magnetization) follows a power law of the form ρH = At-m within a limited time span, where A is a constant and m an exponent. In both IRM and TRM, the exponent m depends appreciably on the applied magnetic field intensity and temperature, for which we have obtained some universal relationship with a newly introduced quantity of \"relative relaxed magnetization\". Furthermore, the decay profiles over the wide time range, where the deviations from the power law occur, are analyzed using the existing \"domain theory\" with some modifications of the theoretical expressions. With the evaluated parameters, discussions are given for the equilibrium relaxation spectra, overlap length, and time-dependent maximum relaxation times that characterize the domain growth and the dynamic properties in this material system.","subitem_description_language":"en"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186819068":{"attribute_name":"Identifier Registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.11501/3119770","subitem_identifier_reg_type":"JaLC"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"1"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicPageStart":"1"}]},"item_1617187087799":{"attribute_name":"Dissertation Number","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第1440号"}]},"item_1617187112279":{"attribute_name":"Degree Name","attribute_value_mlt":[{"subitem_degreename":"博士(理学)","subitem_degreename_language":"ja"},{"subitem_degreename":"Physical Science","subitem_degreename_language":"en"}]},"item_1617187136212":{"attribute_name":"Date Granted","attribute_value_mlt":[{"subitem_dategranted":"1996-03-26"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"(1) Y.
