The free-carrier absorption in the case of spin-disorder scattering is calculated using the density matrix method developed by Kohn and Luttinger (1957). A quantum mechanical equation is derived and then solved by iterations to lowest order. The absorption coefficient alpha at various frequencies is calculated for non-degenerate and degenerate ferromagnetic semiconductors. alpha shows anomalous behaviour at the frequency corresponding to the splitting of the conduction band into spin-up and spin-down sub-bands.
