| 中文摘要 | The electronic and magnetic structure of the charge-ordered spinel AlV2O4 is studied using a combination of high-energy-resolution electron energy-loss spectroscopy and density functional theory. We find that the vanadium atoms have a fractional valence close to 2.4+ and display a charge and magnetic ordering consistent with previous reports. The oxygen K edge features a prominent prepeak indicative of a strong hybridization of O 2p and V 3d hole states. Experiments at high temperatures confirm a structural transition to a non-charge-ordered state, although no effects of this are observed in the spectra. |
