The reflectivity of the itinerant ferromagnet SrRuO3 has been measured between 50 and 25 000 cm^\ensuremath-1 at temperatures ranging from 40 to 300 K, and used to obtain conductivity, scattering rate, and effective mass as a function of frequency and temperature. We find that at low temperatures the conductivity falls unusually slowly as a function of frequency (proportional to 1/\ensuremathω1/2), and at high temperatures it even appears to increase as a function of frequency in the far-infrared limit. The data suggest that the charge dynamics of SrRuO3 are substantially different from those of Fermi-liquid metals.
