A theoretical investigation of the photostimulated thermomagnetic effect by electrons in a semiconductor superlattice (SL) in the lowest miniband is presented. The possibility of controlling the thermopower alpha , the electron thermal conductivity chi and the electroconductivity sigma of the SL with the help of laser radiation is indicated. The parameters alpha , chi and sigma were found to oscillate. The Hall constant, the Righi-Leduc and the Maggie-Righi-Leduc effects were calculated. The prospect of using the SL as a good-quality and highly efficient thermoelement is also proposed.
