## Abstract The title compound is characterized by prompt Ξ³βray activation analysis, ^57^Fe Moessbauer spectroscopy, and magnetic measurements in order to explore the weakening of the ferromagnetic interactions caused by the gradual incorporation of Ga into Ξ³β²βFe~4~N.
The effects of H irradiation on the optical properties of GaAs 1--y N y epilayers in the dilute N limit have been studied. H irradiation leads to a progressive and finally complete passivation of bound exciton levels related to N complexes. A further thermal annealing restores the optical properties
