The Hall coefficient is theoretically calculated in a compositional semiconductor superlattice, subjected to a crossed dc electric field and magnetic field in the presence of an electromagnetic wave (EMW). The magnetic field is oriented along the growth direction of the superlattice. The electron – optical phonon interaction is taken into account at high temperature. Analytical result shows that the Hall coefficient denpends nonlinearly on the EMW amplitude. Numerical results are obtained for GaAs/AlGaAs superlattice and compared to the case of absence of the EMW
