“…The random TCF (RTCF) effects have only been considered in spin-1 models so far. The critical properties of an RTCF Ising model with bond dilution were studied on a square lattice with EFT under both weak and strong bond dilution conditions [14]. The phase transition properties of the spin-1 BEG model were investigated by the use of the EFT on a simple cubic lattice [15].…”

The mean-field approximation is used to calculate the phase diagrams of the spin-3/2 random transverse crystal field (RTCF) model. A bimodal distribution of the RTCF is employed in which one of the modes is in competition with the other mode whose strength is adjusted with a controllable parameter α. Thus, some sites in the lattice are under the effect of RTCF D x with probability p and the rest of the sites are under the effect of α D x with 1 − p. The phase diagrams of the model are obtained on the RTCF-temperature planes by varying p on square lattices. Both second-and first-order phase transitions are displayed and thus tricritical points are also observed. The critical end points and end points for the first-order phase transition lines were also found.
