摘要
The magnetic and electronic properties of Eu2Ru2O7 are discussed in terms of the local ruthenium and europium coordination, electronic band structure calculations, and molecular orbital energy levels. A preliminary electronic structure was calculated within the local density approximation (LDA) and local spin density approximation taking in to account on-site Hubbard U (LSDA+U). The molecular orbital energy level diagrams have been used to interpret the Eu-Ru ligand spectrum and the ensuing magnetic properties. The orbital hybridizations and bonds are discussed.
