Abstract

We have applied our extended generalized pair approximation to dilute magnetic semiconductor epilayers grown by molecular beam epitaxy and in this paper we have compared our calculations of the heavy-hole exciton Zeeman splitting with those we measured on Zn 1− x Mn x Se and those measured by other authors on Cd 1− x Mn x Te epilayers. It appears that there can be found experimental results, including ours, which exhibit a systematic tendency to lie well below the corresponding theoretical curves based on random distribution. We can clearly attribute this reduced paramagnetic behavior to a non-random distribution of the magnetic ions and we present a way to determine the degree of non-random distribution.
