Directional control of spinwave emission has been desired for the realization of switching devices. Here, we propose a promising technique that makes use of a spatially shaped light pulse with circular polarization. Focusing this light pulse on a magnet generates spin waves via the inverse Faraday effect. Moreover, the wavenumber distribution of the spin waves is determined by the spatial intensity distribution of the light spot. We demonstrate the principle of this technique both theoretically and experimentally. We successfully control the direction of the energy flow by shaping the light spot into an ellipse, with its major axis parallel or perpendicular to the magnetic field. Our findings will open up the possibility of fast and arbitrary synthesis of spin-wave patterns by using a more sophisticated light-shaping technique, for example using a computer-generated hologram8.", "subitem_description_type": "Abstract"}]}, "item_2_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Nature Publishing Group"}]}, "item_2_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1038/nphoton.2012.218", "subitem_relation_type_select": "DOI"}}]}, "item_2_select_14": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_2_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA12300925", "subitem_source_identifier_type": "NCID"}]}, "item_2_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1749-4893", "subitem_source_identifier_type": "ISSN"}]}, "item_2_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "Institute of Industrial Science, The University of Tokyo"}, {"subitem_text_value": "PRESTO, Japan Science and Technology Agency"}, {"subitem_text_value": "Institute of Magnetism, NASU"}, {"subitem_text_value": "Institute for Materials Research, Tohoku University"}, {"subitem_text_value": "CREST, Japan Science and Technology Agency"}, {"subitem_text_value": "The Advanced Science Research Center, Japan Atomic Agency"}, {"subitem_text_value": "WPI-Advanced Institute for Materials Research, Tohoku University"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Satoh, Takuya"}], "nameIdentifiers": [{"nameIdentifier": "142984", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Terui, Yuki"}], "nameIdentifiers": [{"nameIdentifier": "142985", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Moriya, Rai"}], "nameIdentifiers": [{"nameIdentifier": "142986", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ivanov, Boris A."}], "nameIdentifiers": [{"nameIdentifier": "142987", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ando, Kazuya"}], "nameIdentifiers": [{"nameIdentifier": "142988", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Saitoh, Eiji"}], "nameIdentifiers": [{"nameIdentifier": "142989", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shimura, Tsutomu"}], "nameIdentifiers": [{"nameIdentifier": "142990", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kuroda, Kazuo"}], "nameIdentifiers": [{"nameIdentifier": "142991", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-10-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "10.1038-nphoton.2012.218.pdf", "filesize": [{"value": "714.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 714900.0, "url": {"label": "10.1038-nphoton.2012.218.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/47712/files/10.1038-nphoton.2012.218.pdf"}, "version_id": "7fe2dd3f-40cb-441e-a76d-22dac5e9f49a"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Directional control of spin-wave emission by spatially shaped light", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Directional control of spin-wave emission by spatially shaped light"}]}, "item_type_id": "2", "owner": "1", "path": ["9/10/11", "171/172/173"], "permalink_uri": "http://hdl.handle.net/2261/00072838", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2017-10-13"}, "publish_date": "2017-10-13", "publish_status": "0", "recid": "47712", "relation": {}, "relation_version_is_last": true, "title": ["Directional control of spin-wave emission by spatially shaped light"], "weko_shared_id": null}
