Theoretical calculations for the ground state energy of a bound magneto-polaron in the ternary mixed crystal A xB 1-xC are presented. The theory is based on a variational approach using a trial wave function in the adiabatic limit. The electronic part of the wave function is the one used in the harmonic approximation. Numerical results are obtained for Ga xAl 1-xAs and show that the effect of phonons decreases on increasing the magnetic field and on decreasing the fraction x of the compounds.
