We have observed a magnetic linear dichroism effect for infrared light in ferromagnetic alloys at room temperature. The effect has been studied for Ni80Fe20, Ni80Co20, Co90Fe10, and Fe88V12 thin films by measuring the transmission of light polarized parallel and perpendicular to the magnetization direction. Its physical origin and frequency dependence are explained from a two-current Drude-type model for the conductivity. A study of a single (thin film) specimen is shown to be sufficient for obtaining the spin and angular dependence of electron relaxation times in ferromagnetic alloys.
