orbital delocalization and magnetic collapse in superconducting (La,Pr)NiO films
Xiaoyang Chen, Wenliang Zhang, Fei Peng +20
The recent discovery of Ruddlesden--Popper (RP) nickelate thin-film superconductors has opened a new frontier in unconventional superconductivity. Its realization requires both com…
Dissecting superconductivity in the Ruddlesden-Popper nickelates: The role of electron correlation and interlayer magnetic exchange
Xiaoyang Chen, Zezhong Li, Mei Xie +9
The discovery of superconductivity in the Ruddlesden-Popper (RP) nickelates has opened a new chapter in the search for high superconducting transition temperatures ()…
X-ray magnetic circular dichroism evidence of intrinsic -wave altermagnetism in rutile-structure NiF
Zezhong Li, Kosuke Sakurai, Yiu-Fung Chiu +13
We present the x-ray magnetic circular dichroism (XMCD) at the Ni -edge as an evidence of the -wave altermagnetism in rutile-structure NiF. Sizable XMCD signal is o…
Preformed Cooper Pairs in a Triclinic Iron Pnictide Superconductor
Zezhong Li, Wenshan Hong, Honglin Zhou +10
Electron pairing along with phase coherence generates superconductivity below the critical temperature (). In underdoped high- cuprates, these two quantum phenomena may o…
