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 Zn1−xMnxSe and those measured by other authors on Cd1−xMnxTe 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.
