论文摘要
我们报告了在伴有压力诱导的磁量子临界点CESB2的磁量子临界点上的超导性的发现，该点持续到超过常规Pauli极限八倍的磁场。像CERH2AS2一样，CESB2在CE位置周围是局部非中心对称，但是随着CESB2的调整，临界场和正常状态特性的演变是通过量子关键点调节的，这激发了其对应用领域的弹性的根本不同的解释。
We report the discovery of superconductivity at a pressure-induced magnetic quantum critical point in the Kondo-lattice system CeSb2, sustained up to magnetic fields that exceed the conventional Pauli limit eight-fold. Like CeRh2As2, CeSb2 is locally non-centrosymmetric around the Ce-site, but the evolution of critical fields and normal state properties as CeSb2 is tuned through the quantum critical point motivates a fundamentally different explanation for its resilience to applied field.
