Nature Communications, Published online: 22 May 2026; doi:10.1038/s41467-026-73493-3 When magnetic impurities are present in a metal, conduction electrons form a spin cloud, also termed a Kondo cloud. Here, the authors provide evidence of Kondo clouds and their coupling in devices made up of mirror-symmetric carbon nanotube arrays separated with a molybdenum strip.
