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(2)B(2)O(7). These quasi flat-bands are mostly characterized by the s-orbitals of the A-site. The band structures of these oxides are well described by the non-int...
