High-pressure synthesis of an unusual antiferromagnetic metal CaCoO${}_3$ with GdFeO${}_3$-type perovskite structure

T. Osaka, H. Takahashi, H. Sagayama +2

The GdFeO${}_3$-type perovskite CaCoO${}_3$ has been successfully synthesized by high-pressure oxygen annealing for the oxygen deficient perovskite. A detailed structural analysis…
