Kagome Superconductor Achieves Unprecedented High-Temperature Performance
Researchers at the Paul Scherrer Institute have discovered that time-reversal symmetry breaking occurs at the surface of the Kagome superconductor RbV₃Sb₅ at a record temperature of 175 K, significantly higher than in the bulk of the material. This phenomenon, which varies with depth, offers tunability and potential applications in quantum technology. The study highlights the ability to manipulate electronic and magnetic properties at more accessible temperatures, contributing to the broader understanding of unconventional superconductivity.
