High temperature transitions in Ruddlesden-Popper nickelates LaNiO
P. Reiss, A. Shevchenko, P. S. Lizama +9
The discovery of superconductivity at in the infinite-layer nickelate , followed by superconductivity at …
Comparative Raman study of Ruddlesden-Popper nickelates and the monolayer-trilayer polymorph
Vignesh Sundaramurthy, Abhi Suthar, Pascal Puphal +12
Ruddlesden-Popper (RP) nickelates have attracted intense interest following the discovery of superconductivity in several members of the series, including bilayer (BL) LaNi…
Multiorbital character of the density wave in trilayer nickelate superconductors
A. Suthar, V. Sundaramurthy, M. Bejas +15
Ruddlesden-Popper nickelates exhibit high-temperature superconductivity closely intertwined with charge and spin density waves. However, fundamental questions persist regarding the…
Floating zone growth at high oxygen pressures in Ruddlesden-Popper bilayer nickelate YSrNiAlO
H. Yilmaz, P. Sosa-Lizama, M. Knauft +7
With the discovery of superconductivity under pressure in the Ruddlesden-Popper (RP) bilayer LaNiO and trilayer LaNiO, a new field of nick…
Unveiling the Interfacial Reconstruction Mechanism Enabling Stable Growth of the Delafossite PdCoO2 on Al2O3 and LaAlO3
Anna Scheid, Tobias Heil, Y. Eren Suyolcu +7
Delafossites, comprised of noble metal (A+) and strongly correlated sublayers (BO2-), form natural superlattices with highly anisotropic properties. These properties hold significa…
Picosecond expansion in LaAlO3 resonantly driven by infrared-active phonons
Jakob Gollwitzer, Jeffrey Z. Kaaret, Y. Eren Suyolcu +19
We investigate the ultrafast structural dynamics of LaAlO3 thin films driven by short mid-infrared laser pulses at 20 THz. Time-resolved X-ray diffraction reveals an immediate latt…
