Abstract

Description

In a recent letter, E. Nazarenko et al [Phys. Rev. Lett. 97, 056403 (2006) and cond-mat/0606596] have investigated the low temperature phase of magnetite by means of resonant X-ray scattering. The paper puts forward the quantitative determination of an effective charge ordering (CO) of 0.24 electron among the octahedral iron atoms in the insulating phase. The comment puts in evidence that the analysis performed by Nazarenko et al is wrong and that some of their conclusions are unsupported .
