It has been known that the spinon, the entity that carries information about electron spin, can \u201cseparate\u201d itself from the others under certain conditions in one-dimensional chains of magnetic ions such as copper (Cu2+) in an insulating host. Now, the new study reveals that spinons are also present in metallic Yb2Pt2Pb.<\/p>\n<p>The experimental team included ORNL postdoctoral researcher and lead author Liusuo Wu, Georg Ehlers, and Andrey Podlesnyak, instrument scientists at ORNL\u2019s Spallation Neutron Source (SNS), a DOE Office of Science User Facility.
