Kinetic phase phenomena of model with the chemical formula [formula omitted] on honeycomb lattice

Abstract

We investigate the ferromagnetic–ferrimagnetic ternary alloy model with the chemical formula ABpC1−p with mean-field theory based on Glauber-type stochastic dynamics, namely dynamic mean-field theory, on a honeycomb lattice consisting of spins SiA=1/2, SjB=3/2 and SjC=5/2. The model includes a selective site disorder, meaning that SiA can randomly have SjC as its nearest neighbor or SjB with probability (1−p). The mean-field dynamic equations were obtained and numerically solved. To identify the type of dynamic phase transitions (first- or second-order), the thermal behavior of dynamic magnetizations was examined. For specified values of the crystal field parameter, exchange interaction parameter, and concentration ratio, the phase diagrams are calculated in the (d−T) and (T−h) planes. The system's fundamental and mixed-phase areas were identified. The system displayed A,TP,QP,Z special points and dynamic tricritical points. It was found that the content of the ternary alloy continuously affected the critical temperature in our dynamic system. Reliable agreements are observed when our findings are compared to those in the literature.
