Here, we present a wide-field, quantitative imaging of the stray field of the vortices in a superconducting thin film using perfectly aligned diamond quantum sensors. Our analysis, which mitigates the influence of the sensor inhomogeneities, visualizes the magnetic flux of single vortices in YBa<sub>2<\/sub>Cu<sub>3<\/sub>O<sub>7\u2212<em>\u03b4<\/em><\/sub>\u00a0with an accuracy of \u00b110%. The obtained vortex shape is consistent with the theoretical model, and penetration depth and its temperature dependence agree with previous studies, proving our technique's accuracy and broad applicability. This wide-field imaging, which in principle works even under extreme conditions, allows the characterization of various superconductors.<\/p>\n\n\n\n<p>See below for more information.<\/p>\n\n\n\n<ul>\n<li>Aritcle URL :\u00a0<a href=\"https:\/\/pubs.aip.org\/aip\/apl\/article\/123\/11\/112603\/2911530\/Wide-field-quantitative-magnetic-imaging-of\">https:\/\/pubs.aip.org\/aip\/apl\/article\/123\/11\/112603\/2911530\/Wide-field-quantitative-magnetic-imaging-of<\/a><\/li>\n\n\n\n<li>Kobayashi Lab. : <a href=\"https:\/\/meso.phys.s.u-tokyo.ac.jp\/en\/\">https:\/\/meso.phys.s.u-tokyo.ac.jp\/en\/<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"Various techniques have been applied to visualize superconducting vortices, providing clues to their electroma [&hellip;]","protected":false},"author":7,"featured_media":4727,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[3],"tags":[11,39],"_links":{"self":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/4726"}],"collection":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/comments?post=4726"}],"version-history":[{"count":1,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/4726\/revisions"}],"predecessor-version":[{"id":4728,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/4726\/revisions\/4728"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/media\/4727"}],"wp:attachment":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/media?parent=4726"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/categories?post=4726"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/tags?post=4726"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
