We calculate the frequency-dependent electrical resistivity, R(ω), of nearly and weakly ferromagnetic metals by applying the Mori formula to the two-band model. Because of the scattering due to spin fluctuations, the complex resistivity at low temperatures has a pronounced frequency dependence, which yields the notable enhancement of the optical mass and the significant deviation from the Drude formula of the conductivity. It is suggested that optical measurements in the far-infrared region may provide a valuable tool for probing the spin-fluctuation spectrum, D(ω), which is shown to be expressed at T=0 K by D(ω)=(Nse2⁄m)×[2∂R′(ω)⁄∂ω+ω∂2R′(ω)⁄∂ω2], where R′(ω) is the real part of R(ω) and is obtainable by the optical experiment.
