Superconducting Temperature Record set at Ambient Pressure
2 min read
Researchers used a pressure-quench protocol to raise Hg1223's superconducting transition temperature to 151 K at ambient pressure. The cuprate, HgBa2Ca2Cu3O8+δ, previously transitioned at 133 K. The method locks in superconducting properties after sudden pressure release, potentially reducing cooling needs for superconductors.
