Fe and Mo valences in Sr2FeMoO6
Abstract:
The valences of Fe and Mo in Sr<inf>2</inf>FeMoO<inf>6</inf> are investigated by means of X-ray absorption and photoemission spectroscopies. We find that the d occupations are similar to those of Fe in Fe<inf>2</inf>O<inf>3</inf> and Mo in MoO<inf>3</inf>. Considering the covalency, however, we argue that the ground state is closer to a Fe<sup>+3</sup>(3d<sup>5</sup>)-Mo<sup>+5</sup>(4d<sup>1</sup>) configuration than to a Fe<sup>+2</sup>(3d<sup>6</sup>)-Mo<sup>+6</sup>(4d<sup>0</sup>) configuration. © 2001 Published by Elsevier Science Ltd.
