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…
Crystallography of periodic nanotextures in a strained Mott insulator
Benjamin Z. Gregory, Yorick A. Birkhölzer, Noah Schnitzer +9
Here we investigate stripes of alternating structural phases spontaneously forming in epitaxially strained thin films below the metal-insulator transition. Using large-…
Tuning charge-transport properties and magnetic order in metallic EuTiO
Xing He, Chiou Yang Tan, Issam Khayr +9
The stoichiometric antiferromagnetic insulator EuTiO is proximate to a ferroelectric phase. Whereas cation substitution has been used as a tuning parameter to introduce charge…
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…
Martensitic laminate geometry controls electronic phase transitions in a Mott insulator
Ziming Shao, Benjamin Gregory, Suchismita Sarker +4
Symmetry-lowering structural phase transitions result in multiple degenerate structures whose coexistence is determined by macroscopic strain compatibility. In quantum materials, t…
