This study identifies CeSiI as a novel heavy-fermion metal exhibiting pressure-induced superconductivity at 240 mK, offering a fresh platform for investigating unconventional pairing mechanisms. The material's unique V-shaped dependence on pressure and its proximity to antiferromagnetic instability provide critical insights into strong electron correlations and quantum criticality within two-dimensional systems. These findings advance the fundamental understanding of how magnetism and superconductivity coexist in strongly correlated electronic environments, which is essential for developing future quantum materials.

Quantum heavy-fermion metal superconducts at 240 milliKelvin

Quantum ZeitgeistAugust 12, 20264 min read

CeSiI, a van der Waals heavy-fermion metal, exhibits superconductivity at 240 mK—emerging when antiferromagnetic order is suppressed.

Researchers led by Tong Shi demonstrate that CeSiI becomes superconducting at 240 milliKelvin under pressure, revealing unusual behavior in this van der Waals heavy-fermion metal. The study details a V-shaped, non-monotonic dependence of the Kondo coherent state on applied pressure, a response differing from most materials. This proximity of superconductivity to antiferromagnetic instability, combined with a large upper critical field, suggests an unconventional pairing mechanism is at work within CeSiI, offering a new platform for exploring strong electron correlations.…
