Persistent structural distortions and absent superconductivity in trilayer nickelate thin films
Abigail Y. Jiang, Maria Bambrick-Santoyo, Lopa Bhatt +14
A new family of high-temperature superconductors was recently discovered in the Ruddlesden-Popper nickelates, where superconductivity emerges concomitant with suppression o…
Pressure and strain tuning of the alternating bilayer-trilayer Ruddlesden-Popper nickelate: crystal and electronic structure
Huan Wu, Yi-Feng Zhao, Antia S. Botana
We use first-principles calculations to investigate the crystal and electronic structure of the hybrid bilayer-trilayer Ruddlesden-Popper (RP) nickelate LaNiO under…
Structural stability, electronic structure, and magnetic properties of the single-layer trilayer La3Ni2O7 polymorph
Shekhar Sharma, Yi-Feng Zhao, Antia S. Botana
A polymorph of the bilayer nickelate La3Ni2O7 that displays an alternating single-layer (SL) and trilayer (TL; 1313) stacking pattern has recently been discovered. Signatures of su…
An altermagnetic materials library in intercalated transition-metal dichalcogenides
Ezra Day-Roberts, Huan Wu, Onur Erten +1
Altermagnets represent a promising class of magnetic materials owing to their distinctive spin-split band structures in the absence of net magnetization. Here, we present a first-p…
Preferential site ordering alters the magnetic structure of SmRuSnGe (-2)
Jacob W. Fritsky, Hui-Fei Zhai, Yifeng Zhao +3
An important aspect of materials research is the ability to tune different physical properties through controlled alloying. The LnMX (Ln = Lanthanide, M = Transition…
Topotactic oxidation of Ruddlesden-Popper nickelates reveals new structural family: oxygen-intercalated layered perovskites
Dan Ferenc Segedin, Jinkwon Kim, Harrison LaBollita +20
Layered perovskites such as the Dion-Jacobson, Ruddlesden-Popper, and Aurivillius families host a wide range of correlated electron phenomena, from high-temperature superconductivi…
