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…
Room-temperature multistage metastability in a moiré superstructure
B. Q. Lv, Yifan Su, Alfred Zong +16
Metastability is fundamental not only to phase ordering and transitions, but also to a broad range of modern technologies, from memory devices to metallic glasses. In condensed-mat…
Structural Phase Separation Couples to Charge-Density-Wave Formation in Kagome Metal FeGe
Boyang Zhao, Youngjun Ahn, Qinwen Deng +7
The intertwining of charge, spin, and lattice degrees of freedom underlies the emergent properties of correlated materials. A recent prominent example is the kagome metal FeGe, whi…
The Evolution of Magnetism in a Thin Film Pyrochlore Ferromagnetic Insulator
Margaret A. Anderson, Megan E. Goh, Yang Zhang +19
The pyrochlore vanadates are compelling candidates for next-generation dissipationless devices. Lu2V2O7 and Y2V2O7 are ferromagnetic insulators (Tc ~ 70 K) that are believed to exh…
Photoinduced metastable cation disorder in metal halide double perovskites
Shunran Li, Burak Guzelturk, Conrad A. Kocoj +18
Lead-free perovskites have emerged as environmentally benign alternatives to lead-halide counterparts for optoelectronics. Among them, the double perovskite Cs2AgInCl6 family exhib…
Emergent Atomic Scale Polarisation Vortices in BaTiS3
Boyang Zhao, Gwan Yeong Jung, Shantanu Singh +21
Topological defects, such as vortices and skyrmions in magnetic and dipolar systems, can give rise to properties that are not observed in typical magnets and dielectrics. Here, we…
