A mechanism for electric-dipole processes involving a spin flip in a semimagnetic semiconductor is proposed. The mechanism involves an exchange interaction of a carrier with a magnetic impurity. Its contribution to the absorption is comparable to that from the spin-orbit interaction, but it has several distinctive features.
