TL;DR: Crystal structure analysis reveals that bond strain, rather than the charge account of the A-site alone, play an important role in determining which of intersite charge transfer or charge disproportionation is practical.
Journal ArticleDOI
Direct observation of the ferrimagnetic coupling of A -site Cu and B -site Fe spins in charge-disproportionated CaCu 3 Fe 4 O 12
Journal ArticleDOI
Synthesis, Structure, and Physical Properties of A-site Ordered Perovskites ACu3Co4O12 (A = Ca and Y)
TL;DR: A-site ordered perovskites CaCu3Ti4O12 and YCu3Co 4O12 were synthesized under high pressure (9 GPa) and high temperature (1273 K) as discussed by the authors.
Journal ArticleDOI
Complementary evaluation of structure stability of perovskite oxides using bond-valence and density-functional-theory calculations.
TL;DR: This work compares the GII and total energy of typical ABO3-type perovskite oxides and rationalizes their relationship, proposing that the criteria for empirically unstable structures (GII > 0.2 valence unit) correspond to the difference in totalEnergy of 50–200 meV per formula unit.

High-pressure synthesis of BaVO3: A new cubic perovskite
TL;DR: A cubic perovskite BaVO 3 was synthesized by high-pressure synthesis at 15 GPa and 1350°C as mentioned in this paper, which preserved its cubic crystal structure with a =3.94288(3)A at room temperature and had Fermi-liquid characteristics as SrVO 3 down to the lowest temperature.
