Oxygen Stoichiometry in the Geometrically Frustrated Kagomé System YBaCo4O7+δ: Impact on Phase Behavior and Magnetism

Ternary Co oxides of the general formula RBaCo4O7+δ (where R = rare earth or Y) represent a family of materials that demonstrate impressive oxygen storage capabilitiesas much as 3.25% by weightat a relatively low temperature of ∼350 °C. This behavior results from structural features amenable to fo...
