By using a single-shot time-domain terahertz spectroscopy setup combined with a table-top pulsed minicoil magnet, we conducted measurements in magnetic fields up to 30 T, observing distinctly different behaviors between semimetallic (x<0.07) and topological insulator (x>0.07) samples. Faraday and Kerr rotation spectra for the semimetallic films showed a pronounced dip that blueshifted with the magnetic field, whereas spectra for the topological insulator films were positive and featureless, increasing in amplitude with increasing magnetic field and eventually saturating at high fields (>20 T). Ellipticity spectra for the semimetallic films showed resonances, whereas the topological insulator films showed no detectable ellipticity. To explain these observations, we developed a theoretical model based on realistic band parameters and the Kubo formula for calculating the optical conductivity of Landau-quantized charge carriers. Our calculations quantitatively reproduced all experimental features, establishing that the Faraday and Kerr signals in the semimetallic films predominantly arise from bulk hole cyclotron resonances while the signals in the topological insulator films represent combined effects of surface carriers originating from multiple electron and hole pockets. These results demonstrate that the use of high magnetic fields in terahertz magnetopolarimetry, combined with detailed electronic structure and conductivity calculations, allows us to unambiguously identify and quantitatively determine unique contributions from different species of carriers of topological and nontopological nature in Bi_{1−x} Sb_x.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"APS"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1103/PhysRevB.100.115145","subitem_relation_type_select":"DOI"}}]},"item_2_relation_44":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://doi.org/10.1103/PhysRevB.100.115145"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1103/PhysRevB.100.115145","subitem_relation_type_select":"DOI"}}]},"item_2_rights_14":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"©2019 American Physical Society"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"24699969","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Electrical and Computer Engineering, Rice University, Houston, Texas 77005, USA"},{"subitem_text_value":"Department of Physics, Graduate School of Engineering, Yokohama National University, Yokohama 240-8501, Japan"},{"subitem_text_value":"Department of Physics and Center for Complex Quantum Systems, The University of Texas at Austin, Austin, Texas 78712, USA"},{"subitem_text_value":"Department of Electrical and Computer Engineering, Rice University, Houston, Texas 77005, USA"},{"subitem_text_value":"Department of Physics and Center for Complex Quantum Systems, The University of Texas at Austin, Austin, Texas 78712, USA"},{"subitem_text_value":"Department of Physics and Astronomy, Rice University, Houston, Texas 77005, USA"},{"subitem_text_value":"Department of Electrical and Computer Engineering, Rice University, Houston, Texas 77005, USA"},{"subitem_text_value":"Department of Physics, Graduate School of Engineering, Yokohama National University, Yokohama 240-8501, Japan"},{"subitem_text_value":"National Institute for Materials Science, Tsukuba, Ibaraki 305-0044, Japan"},{"subitem_text_value":"National Institute for Materials Science, Tsukuba, Ibaraki 305-0044, Japan"},{"subitem_text_value":"National Institute for Materials Science, Tsukuba, Ibaraki 305-0044, Japan"},{"subitem_text_value":"Department of Physics, Graduate School of Engineering, Yokohama National University, Yokohama 240-8501, Japan / National Institute for Materials Science, Tsukuba, Ibaraki 305-0044, Japan"},{"subitem_text_value":"Institute for Materials Research, Tohoku University, Sendai 980-8577, Japan"},{"subitem_text_value":"Department of Physics and Center for Complex Quantum Systems, The University of Texas at Austin, Austin, Texas 78712, USA"},{"subitem_text_value":"Department of Physics and Center for Complex Quantum Systems, The University of Texas at Austin, Austin, Texas 78712, USA"},{"subitem_text_value":"Department of Physics, Graduate School of Engineering, Yokohama National University, Yokohama 240-8501, Japan"},{"subitem_text_value":"Department of Physics, Graduate School of Engineering, Yokohama National University, Yokohama 240-8501, Japan"},{"subitem_text_value":"Department of Physics and Center for Complex Quantum Systems, The University of Texas at Austin, Austin, Texas 78712, USA / Department of Physics, Northeastern University, Boston, Massachusetts 02115, USA / Department of Physics, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA"},{"subitem_text_value":"Department of Electrical and Computer Engineering, Rice University, Houston, Texas 77005, USA / Department of Physics and Astronomy, Rice University, Houston, Texas 77005, USA / Department of Material Science and NanoEngineering, Rice University, Houston, Texas 77005, USA"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Li, Xinwei"}],"nameIdentifiers":[{"nameIdentifier":"36341","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshioka, Katsumasa"}],"nameIdentifiers":[{"nameIdentifier":"36342","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Xie, Ming"}],"nameIdentifiers":[{"nameIdentifier":"36343","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noe, G.
