Multicritical points in the mixed ferromagnetic-ferrimagnetic ternary alloy with a single-ion anisotropy

Phase diagrams and multicritical points in the ternary mixed‐spin alloy with a single‐ion anisotropy

“…1 . On the other hand, it is remarkable that contrary to the mixed spin-3 2 and spin-1 Ising system [5], the present mixed-spin Ising system does not exhibit a tricritical point and the phase diagram in Fig. 1 contains the critical end point instead of the triple point.…”

“…The [ , 0] phases coexist, and at the isolated critical point the two phases coalesce. As has been pointed out in [5], this higher-temperature ordered phase comes into existence from the ground-state [± 1 2 , 0] disordered phase and, therefore, has been denoted in Fig. 1 .…”

The Effect of a Random Crystal-Field on the Mixed Ising Spins (1/2, 3/2)

“…The mean-field theory approach, based on the bogolyubov inequality for the gibbs free energy [21], showed that the obtained phase diagrams exhibit a variety of multicritical points such as tricritical points and isolated critical points. on the other hand, we have shown in some of our recent works [22,23] the existence of interesting properties in the magnetization behavior and phase diagrams in the presence of a random crystal-field.…”
