Description

We compute the phase diagram of the nonmetallic compounds ZnCr2pA12-2pS(Se)4 (I[S,Se]) and Zn1-pCdpCr2S(Se)4 (II[S,Se]). We consider the bond-diluted Ising model on the spinel B site (S.B.S.) lattice with competitive exchange interactions, i.e. the ferromagnetic exchange interaction J1 between nearest neighbours (n.n.) and the antiferromagnetic superexchange interaction J2 between next-nearest neighbours' (n.n.n.) (and/or the more distant superexchange interactions Ji (i > 1). Dilution and competition are found to be responsible for the spill glass phase and the percolation behaviour. (author)
