Bulk superconductivity up to 96 K in pressurized nickelate single crystals
Feiyu Li, Zhenfang Xing, Di Peng +24
Recently, the Ruddlesden-Popper bilayer nickelate has emerged as a superconductor with a transition temperature () of approximately 80 K above 14 GPa (Refs. 1-3)…

Evolution from Topological Dirac Metal to Flat-band-Induced Antiferromagnet in Layered KxNi4S2 (0<=x<=1)
Hengdi Zhao, Xiuquan Zhou, Hyowon Park +17
Condensed matter systems with coexisting Dirac cones and flat bands, and a switchable control between them within a single system, are desirable but remarkably uncommon. Here we re…
