Abstract
Using polarization-dependent V2p and O1s near-edge x-ray absorption spectroscopy, we studied the unoccupied electronic structure of single-crystalline (VO)2P2O7. It is highly anisotropic, and shows similarities to vanadium oxides like VO2 and V2O5 at the V2p edge and at the O1s threshold. The contributions from V-O and P-O orbitals could be identified. The results rule out the spin ladder model for the magnetic behavior of (VO)2P2O7, but are consistent with the alternating chain scenario. © 2001 The American Physical Society.
