Flat-Band in Pyrochlore Oxides: A First-Principles Study

Using a first-principles electronic band calculation, we obtained a quasi flat-band near the Fermi level for the six pyrochlore oxides, A<sub>2</sub>B<sub>2</sub>O<sub>7</sub>. These quasi flat-bands are mostly characterized by the s-orbitals of the A-site. The ba...
