High-effi ciency thermoelectric materials are attracting increasing attention for the potential applications, especially for energy accumulation using waste heat. Tsujii [1] has proposed the use of magnetic semiconductors as effi cient thermoelectrics. Magnetic semiconductors are materials, in which magnetic ions such as Mn, Fe, and Co, are in the composition of the major semiconductor. These materials have been studied for use in spintronics but their thermoelectric properties have not been studied extensively. A characteristic feature of magnetic semiconductors is a strong interaction between the charge carriers and the spins of the magnetic ions. This interaction can lead to a large effective mass of the charge carriers, which enhances the Seebeck coeffi cient with good conductivity of the charge carriers. A representative of this class is the well-known semiconductor chalcopyrite CuFeS2.
