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)…
Reply to "Threefold error in the reported zero-field cooled magnetic moment of single crystal (arXiv: 2602.23240)"
Feiyu Li, Zhenfang Xing, Di Peng +24
We respond to the critique by Aleksandr V. Korolev and Evgeny F. Talantsev on the superconducting phase fraction () calculations in Li et al. Nature 649, 871-878 (2026). First,…
Direct Observation of d-Wave Superconducting Gap Symmetry in Pressurized La3Ni2O7-delta Single Crystals
Zi-Yu Cao, Di Peng, Seokmin Choi +21
The recent discovery of superconductivity in pressure-stabilized bulk La3Ni2O7-delta, with a critical temperature (Tc) exceeding 77 K, has opened a new frontier in high-temperature…
Isotropic superconductivity in pressurized trilayer nickelate La4Ni3O10
Di Peng, Yaolong Bian, Zhenfang Xing +23
Evidence of superconductivity (SC) has recently been reported in pressurized La3Ni2O7 and La4Ni3O10, providing a new platform to explore high-temperature superconductivity. However…
