“…In contrast to earlier phase diagrams [12][13][14]16] the different magnetic phases have been determined accurately. The phase diagram determined by Afif et al [21,22] using Ising model cannot describe correctly the system as it is a 3D Heisenberg system.…”

“…A phase diagram of the system Cd 1Àx Zn x Cr 2 Se 4 has been computed by considering the bond-diluted Ising model on the spinel B lattice with competitive exchange interactions [21]. The quenched randomness may cause fundamental changes in low-temperature magnetic behaviour in this system [22]. Nevertheless, there is a lack of definite information about the different transitions in the middle concentration range.…”

We have investigated the magnetic and electronic properties of diluted magnetic semiconductors (DMS) Cd 1-x Mn x Te and Zn 1-x Mn x Te. The magnetic phase diagrams have been determined by the replica method in the framework of the Ising model using the variational principle. The obtained results are in agreement with the experimental ones. A spin glass state has been obtained for x < x c (x c = 0.6). This phase is attributed to the randomness and the frustration of the antiferromagnetic interactions between the Mn magnetic ions arising from the topology of the DMS alloys. The sp 3 semi-empirical nearest-neighbour tight-binding formalism is used to compute the band structures of the above two systems in the hole range of concentration 0 ≤ x ≤ 1. The variation of the gap energy E g with x is presented. The magnetic blueshift for x > x c is discussed in relation with the published magnetic results.
