Breakthrough: Nickelate Superconductivity Achieved at 96 K!

12/3/2025

Summary

Story summary

The bilayer nickelate La2SmNi2O7-? exhibits superconductivity up to 96 K under high pressure.
Researchers synthesized it at ambient pressure, addressing synthesis challenges.
The study addresses higher Tc limits in nickelates and the production of high-quality crystals without high oxygen-pressure conditions.
Findings include bulk superconductivity, zero resistivity, and the Meissner effect across pressures.
A correlation links higher Tc with increased in-plane lattice distortion, guiding future improvements.
