New Kind of Magnetism Spotted in an Engineered Material
In an atomically thin stack of semiconductors, a mechanism unseen in any natural substance causes electrons’ spins to align.
Room-Temperature Superconductor Discovery Meets With Resistance
A paper in Nature reports the discovery of a superconductor that operates at room temperatures and near-room pressures. The claim has divided the research community.
High-Temperature Superconductivity Understood at Last
A new atomic-scale experiment all but settles the origin of the strong form of superconductivity seen in cuprate crystals, confirming a 35-year-old theory.
Graphene Superconductors May Be Less Exotic Than Physicists Hoped
Superconductivity has been discovered in graphene devices without any twists, suggesting the form of superconductivity in the material might be mundane after all.
Room-Temperature Superconductivity Claim Falls Apart [Update]
In 2020, researchers reported that they had created a room-temperature superconductor. That paper has now been retracted.
