A theory of the hot electron transport in strong magnetic fields is presented and isapplied to the magnetophonon resonance (MPR) in semiconductors in high electricfields. The balance equations for energy and momentum are derived based onZubarev's theory of nonequilibirium density matrices without employing a conven-tional warm electron approximation. Explicit numerical results are presented forGaAs and splitting of the MPR peak and the reduction of MPR amplitude with the in-crease of the electric field are demonstrated. The drift velocity due to scattering fromacoustic phonons is much smaller than that due to LO phonon scattering, showingthat the quasi-elastic-inter-Landau-level scattering does not take place in thismaterial.rnagnetophonon resonance, resonant cooling, resonant heating, optical phonon
