Similar DPDs with Figure 4a were reported in the mixed spin (1/2, 1), [ 73 ] (1, 3/2), [ 74 ] and (1, 2) [ 72 ] IFS, and the similar DPD with Figure 4b were observed in the mixed spin (1/2, 1), [ 69,73,75–77 ] (1, 3/2), [ 78 ] (1, 2), [ 72 ] and (2, 5/2) [ 38,40,48 ] IFS. Moreover, qualitatively similar DPDs with Figure 4c–e were found in the mixed‐spin (1, 2) IFS, [ 72 ] and a similar DPD with Figure 4c were reported in the mixed‐spin (1, 3/2) IFS [ 79 ] ther hand, some of the first‐order phase transition lines, which might be artifact of the DMFA, were observed in the mixed spin (2, 5/2) bilayer system by the DMFA, [ 43 ] but are not observed by the PPM, compare Figure 4 and 5 in ref.…”

A study, within the path probability method, of the dynamic magnetic features of the mixed spin (2, 5/2) Ising ferrimagnetic system on a hexagonal lattice under the presence of a sinusoidal external magnetic field is presented. The Hamiltonian of the system contains intersublattice, intrasublattice, and crystal‐field interactions. The intersublattice interaction is taken as antiferromagnetic. The time variations of average dynamic magnetizations and the thermal behavior of the dynamic magnetizations are investigated to obtain the phases in the system and to characterize the nature of the dynamic phase transitions and find the dynamic phase transition temperature points. The dynamic phase diagrams in six different phase planes are presented, in which they contain the paramagnetic (p) phase, three different ferrimagnetic (i 1, i 2, i 3) fundamentals, and the p + i 1, i 1 + i 2, and i 2 + i 3 mixed phases as well as the dynamic tricritical point and the dynamic double critical end point, depending on the interaction parameters. The dynamic compensation behavior is also examined and only N‐type behaviors are observed. Some of the obtained dynamic phase diagrams are in qualitatively good agreement within some works on the dynamics of mixed‐spin Ising system.
