Cryogenic focused-ion-beam microstructuring enabling quantitative -axis transport measurements in TlBaCuO
Ayanesh Maiti, Carsten Putzke, Linus Holeschovsky +10
Absolute transport measurements in correlated quantum materials are often limited by disorder, inhomogeneity, geometric uncertainty, and small crystal size. Focused ion beam (FIB)…
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…
Probing La-based nickelates with Ni 1 core-level photoelectron spectroscopy
Daisuke Takegami, Naoki Ito, Koto Fujinuma +15
We present a comparative Ni core level photoemission study of LaNiO, NdNiO, and LaNiO using both the Ni and the Ni . We address the challenges…
Superconductivity and normal-state transport in compressively strained LaPrNiO thin films
Yidi Liu, Eun Kyo Ko, Yaoju Tarn +8
The discovery of superconductivity under high pressure in Ruddlesden-Popper phases of bulk nickelates has sparked great interest in stabilizing ambient pressure superconductivity i…
Disorder-induced suppression of superconductivity in infinite-layer nickelates
Abhishek Ranna, Romain Grasset, Martin Gonzalez +10
The pairing symmetry of superconducting infinite-layer nickelates is a fundamental yet experimentally challenging question. We employ high-energy electron irradiation to induce dis…
Magnetic excitations in NdNiO Ruddlesden-Popper nickelates observed via resonant inelastic x-ray scattering
Sophia F. R. TenHuisen, Grace A. Pan, Qi Song +16
Magnetic interactions are thought to play a key role in the properties of many unconventional superconductors, including cuprates, iron pnictides, and square-planar nickelates. Sup…
