We are now studying these new superconductors using a low temperature scanning tunneling microscope (STM), built with the help of two 91̽»¨ Mudd alums, now graduate students at Harvard.  We have used this STM to image the superconducting density of electronic states with atomic resolution.  We have also imaged a disordered lattice of magnetic vortices, which demonstrates strong bulk pinning in these new materials, a necessary condition for practical superconducting applications.<\/p>\n","protected":false},"author":1,"featured_media":0,"template":"","class_list":["post-3896","physics_colloquium","type-physics_colloquium","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/physics_colloquium\/3896","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/physics_colloquium"}],"about":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/types\/physics_colloquium"}],"author":[{"embeddable":true,"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/users\/1"}],"wp:attachment":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/media?parent=3896"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
