| Direct observation of the suppression of the Auger effect on shallow donors by the magnetic field in the luminescence of manganese ions in semiconducting CdF2:Mn crystals is presented. The magnetic field decreases the probability of the Auger effect, which is spin-dependent energy transfer from the manganese ions to the electrons occupying shallow donors. This results in the increase in the decay times of the luminescence. |
