They also establish rhombohedral multilayer graphene as a promising platform for investigating the fundamental mechanisms of superconductivity and magnetism. Potentially, it could be used to develop new ways of controlling quantum materials.<\/p>\n<p>\u201c<a href=\"https:\/\/www.nature.com\/articles\/s41567-026-03443-9\" rel=\"nofollow noopener\" target=\"_blank\">Superconductivity and Ferroelectric Orbital Magnetism in Semimetallic Rhombohedral Hexalayer Graphene<\/a>\u201d was published in Nature Physics on Oct. 22.
