The electrodynamic properties of Au1-x Fex films are measured for various Fe contents x=0, 6, 17, and 22□at.%. From room-temperature optical measurements over a broad spectral range (10-3.3× 104 □ cm-1), we obtain the frequency-dependent conductivity of the films. As the iron concentration increases, a stronger decrease in the magnetic contribution to the dc conductivity compared to ac conductivity (at frequency 10□ cm-1) is detected. In addition, a broad absorption peak is discovered at frequency 1000-3000□ cm-1 for concentrations of 6-22□at.%. Both observations are associated with ferromagnetic clusters that cause partial localization of conduction electrons.
