The phase diagrams of a random-bond mixed spin Ising system consisting of spin-~ and spin-I wtth a transverse field are investigated within the framework of an effective-field approximation. Our phase diagram of zero transverse field is completely equivalent to that based on the finite cluster appro

A new type of effective-field theory that has recently been used with success for many applications concerning the two-state transverse Ising model (spin-ยฝ TIM), is herein extended to the spin-1 TIM. The method, which can explicitly and systematically include correlation effects, is illustrated by e
Within the framework of the effective-field theory with correlations, the ferromagnetic spin-2 Ising model with a transverse crystal field on honeycomb, square and simple cubic lattices is studied. We have investigated the effect of the transverse crystal field on the phase diagrams, magnetization,
