Signatures of polarized chiral spin disproportionation in rare earth nickelates
Jiarui Li, Robert J. Green, Claribel Domínguez +12
In rare earth nickelates (RENiO), electron-lattice coupling drives a concurrent metal-to-insulator and bond disproportionation phase transition whose microscopic origin has lon…
Optical properties of LaNiO3 films tuned from compressive to tensile strain
I. Ardizzone, M. Zingl, J. Teyssier +11
Materials with strong electronic correlations host remarkable -- and technologically relevant -- phenomena such as magnetism, superconductivity and metal-insulator transitions. Har…
Length-scales of interfacial coupling between metal-insulator phases in oxides
Claribel Domínguez, Alexandru B. Georgescu, Bernat Mundet +10
Controlling phase transitions in transition metal oxides remains a central feature of both technological and fundamental scientific relevance. A well-known example is the metal-ins…
Scale-invariant magnetic textures in the strongly correlated oxide NdNiO
Jiarui Li, Jonathan Pelliciari, Claudio Mazzoli +9
Strongly correlated quantum solids are characterized by an inherently granular electronic fabric, with spatial patterns that can span multiple length scales in proximity to a criti…
Complex magnetic order in nickelate slabs
Matthias Hepting, Robert J. Green, Zhicheng Zhong +18
Magnetic ordering phenomena have a profound influence on the macroscopic properties of correlated-electron materials, but their realistic prediction remains a formidable challenge.…
Impact of antiferromagnetism on the optical properties of rare earth nickelates
J. Ruppen, J. Teyssier, I. Ardizzone. O. E. Peil +5
We study the temperature dependence of the optical conductivity of rare-earth nickelate films of varying composition and strain close to the antiferromagnetic ordering temperature,…
Multiple supersonic phase fronts launched at a complex-oxide hetero-interface
M. Först, K. R. Beyerlein, R. Mankowsky +16
Selective optical excitation of a substrate lattice can drive phase changes across hetero-interfaces. This phenomenon is a non-equilibrium analogue of static strain control in hete…
Ground state oxygen holes and the metal-insulator transition in the negative charge transfer rare-earth nickelates
Valentina Bisogni, Sara Catalano, Robert J. Green +9
The metal-insulator transitions and the intriguing physical properties of rare-earth perovskite nickelates have attracted considerable attention in recent years. Nonetheless, a com…
Broadband THz spectroscopy of the insulator-metal transition driven by coherent lattice deformation at the SmNiO3/LaAlO3 interface
W. Hu, S. Catalano, M. Gibert +2
We investigate the non-equilibrium insulator-metal transition driven in a SmNiO3 thin film by coherent optical excitation of the LaAlO3 substrate lattice. By probing the transient…
Striped nanoscale phase separation at the metal-insulator transition of heteroepitaxial nickelates
Giordano Mattoni, Pavlo Zubko, Francesco Maccherozzi +11
Nucleation processes of mixed-phase states are an intrinsic characteristic of first-order phase transitions, typically related to local symmetry breaking. Direct observation of eme…
Optical spectroscopy and the nature of the insulating state of rare-earth nickelates
J. Ruppen, J. Teyssier, O. E. Peil +6
Using a combination of spectroscopic ellipsometry and DC transport measurements, we determine the temperature dependence of the optical conductivity of NdNiO and SmNiO fi…
Electronic Transitions in Strained SmNiO_3 Thin Films
S. Catalano, M. Gibert, V. Bisogni +10
Nickelates are known for their metal to insulator transition (MIT) and an unusual magnetic ordering, occurring at T=T_Néel. Here, we investigate thin films of SmNiO_3 subjected to…
