Charge disproportionation and the pressure-induced insulator?metal transition in cubic perovskite PbCrO3
(National Academy of Sciences, 2014-12)
The perovskite PbCrO3 is an antiferromagnetic insulator. However, the fundamental interactions leading to the insulating state in this single-valent perovskite are unclear. Moreover, the origin of the unprecedented volume ...
Modeling the crystallographic structure of Ho(Ni,Co,Mn)O3±δ perovskite-type manganite
(2012)
Crystallographic and microstructural properties of Ho(Ni,Co,Mn)O3± perovskite-type multiferroic material are reported. Samples were synthesized with a modified polymeric precursor method. The synchrotron X-ray powder ...
