Abstract: | Within the framework of an effective field approximation, the effects of single-ion anisotropy and different trimodal transverse fields of two sublattices on the critical properties of the mixed spin-1/2 and spin-1 Ising system are investigated on the simple cubic lattice. A smaller single-ion anisotropy can magnify magnetic ordering
phases and a larger one can depress magnetic ordering phase for
T-Ω1/2 space at low temperatures, while a smaller single-ion
anisotropy can hardly change the value of critical transverse field for
T-Ω1 space. On the other hand, influences of two different trimodal transverse fields concentrations on tricritical points and magnetic ordering
phases take on some interesting results in T-D space. The main reason
comes from the common action of single-ion anisotropy, different transverse
fields and two trimodal distributions. |
