3D imaging reveals unexpected structural complexity in a long-studied superconductor
A material studied for roughly 40 years has proven more structurally complex than scientists expected. Advanced 3D imaging showed that it contains a patchwork of different crystal structures separated by unusually wide boundaries.
Researchers suggest that these broad boundaries may weaken superconductivity. If confirmed, the discovery could help account for performance differences among superconductors and require researchers to revisit assumptions about the material’s internal organization.
