Abstract: With high-resolution photoemission spectroscopy measurements, the density ofstates DOS near the Fermi level $E \mathrm{F}$ of double perovskiteSr$ 2$FeMoO$ 6$ having different degrees of Fe-Mo antisite disorder has beeninvestigated with varying temperature. The DOS near $E \mathrm{F}$ showed asystematic depletion with increasing degree of disorder, and recovered withincreasing temperature. Altshuler-Aronov AA theory of disordered metals wellexplains the dependences of the experimental results. Scaling analysis of thespectra provides experimental indication for the functional form of the AA DOSsingularity.
