Charge and orbital order in half-doped manganites

a clear picture of the physics behind the metallic ferromagnetic properties of

Interplay between spin, charge and orbital degrees of freedom in magnetic oxides

Double-exchange model: phase separation versus canted spins

{\mathrm{CrO}}_{2}

Multiferroicity in rare-earth nickelates RNiO3

is a negative charge transfer gap material which leads to self-doping and explains why it is a metal in spite of the large Coulomb interactions. We find that there exist in
