Site Preferences and "Coloring Problem" in Cu-doped BiMnO Quadruple Perovskite
Cheng Peng, Mingyu Xu, Yang Zhang +3
Lightly Cu-doped BiMnO (x = 0.05, 0.10, and 0.15) was investigated using high-pressure synthesis, single-crystal X-ray diffraction, pair distribution function (PDF) anal…
Nanoscale Polar Landscapes in Quantum Paraelectric SrTiO3
Yang Zhang, Suk Hyun Sung, Nishkarsh Agarwal +5
SrTiO3 is a textbook quantum paraelectric, with ferroelectricity purportedly suppressed by quantum fluctuations of ionic positions down to the lowest temperatures. The precise real…
Helium-Cooled Cryogenic STEM Imaging and Ptychography for Atomic-Scale Study of Low-Temperature Phases
Noah Schnitzer, Mariana Palos, Geri Topore +7
Much of the exotic functionality of prime interest in quantum materials emerges from structural and electronic ground states that can only be accessed at cryogenic temperatures. Un…
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…
Kondo driven suppression of charge density wave in Van der Waals material UTe
Justin Shotton, Jiahui Zhu, David Martinez +22
Competing electronic instabilities lie at the heart of emergent phenomena in quantum materials. In low-dimensional metals, Fermi-surface nesting can drive charge density wave (CDW)…
Kondo Reshapes Multiple Orders in a van der Waals Material
Gal Tuvia, Ruizhe Kang, Diana Golovanova +14
Electron interactions can drive magnetism, superconductivity, and topology. However, the realization of these phases remains limited in van der Waals materials, and the full landsc…
