We have performed local-density-functional band-structure calculations for a new high-To superconducting phase, YBa2Cu4Oa. General characteristics in the energy band are quite similar to those of YBa2CusOT. We have found a noticeable energy-level lowering of oxygen p-states at the chain and apex sit
We have obtained the electron-energy-loss spectra below 1,000 eV for YBa2C~307-~. The spectra show contributions from all elemental constituents, although the Y-signal is very weak owing to its small concentration. The low-loss region and the Ba-core losses are very similar to those obtained for BaO
