Impersonating a Superconductor: High-Pressure BaCoO${}_3$, an Insulating Ferromagnet

Haozhe Wang, Xianghan Xu, Danrui Ni +4

We report the high-pressure synthesis (6 GPa, 1200 ${}^{\circ }$C) and ambient pressure characterization of hexagonal HP-BaCoO${}_3$. The material (with the 2H crystal structure) has a…
