Non-equilibrium phase transition properties of disordered binary ferromagnetic alloy

•Disordered binary ferromagnetic alloy is studied within the framework of EFT.•Glauber-type stochastic process is used.•Depending on the system parameters, dynamic multicritical phenomena are observed.•The system may exhibit coexistence region, where F+P phases overlap.

Non-equilibrium dynamic phase transition features of a disordered binary ferromagnetic alloy consisting of spin-1/21/2 and spin-1 components under the presence of a time dependent oscillating magnetic field have been analyzed for a two dimensional square lattice. With the help of Glauber-type stochastic process, the kinetic equations of time dependent magnetizations have been derived based on the effective-field theory with single-site correlations. A systematic analysis for the whole range of the concentrations of randomly distributed components as well as other system parameters has been carried out. According to our numerical investigations, the considered system presents unusual thermal and magnetic field behaviors such as the existence of dynamic multi-critical behavior and also boundaries of the coexistence region, where both dynamically ordered and disordered phases overlap, sensitively depends on the studied parameter space.
