“…Finally, it should be also mention that we have found that the metastable phase diagrams of the spin-3 2 Ising BEG model for K/Jp0, which has served as a paradigm for a large number of physically important phenomena, always exists at the low temperatures that are consistent with experimental and theoretical works on some alloys [39][40][41], semiconductors [42][43][44][45], polymers [46], water [47] and the ternary system [47]. Moreover, the spin-1 BEG model have been used to calculate the metastable phase diagrams of some real systems such as Cu-Al-Mn shape-memory alloys [41], semiconductor alloys [44,45] and the ternary system [48] and the unstable continuation of the second-order phase transition line in (A III B V ) 1Àx C IV 2 x -semiconductor alloys [45].…”
