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…

Tetragonal BaCoO: A Co Ferromagnetic Mott Insulator with Inverted Spin Crossover
Mingyu Xu, Haozhe Wang, Krishna Prasad Koirala +13
The interplay between crystal electric field splitting of d states and Hund's rule exchange energy in cobalt-based perovskites offers a promising avenue for inducing spin-state tra…

Impersonating a Superconductor: High-Pressure BaCoO, an Insulating Ferromagnet
Haozhe Wang, Xianghan Xu, Danrui Ni +4
We report the high-pressure synthesis (6 GPa, 1200 C) and ambient pressure characterization of hexagonal HP-BaCoO. The material (with the 2H crystal structure) has a…
