Phase Diagram of ZnCr2pAl22pS4 and Zn1pCdpCr2Se4

Magnetic structure and phase diagram of the frustrated spinel Cd1−xZnxCr2Se4

“…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.…”

“…Taking into account the exchange integrals, the transfer integrals were calculated [20]. 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].…”
