The shift in temperature (T) of relaxation time (?) maximum was detected and its behavior near the secondorder transition points are presented at different magnetic field values (h) and different lattice coordination numbers (q). An expression for the dynamic (or complex) susceptibility (? = ?1 - i?2) is also derived. The temperature dependence of the magnetic dispersion (?1) and magnetic absorption (?2) factors have been studied near the critical regime. It is found that the maximum of ?1 as a function of frequency (?) and kinetic coefficient (L) obeying an approximately exponential increases and decreases in T- ? and T-L planes near the critical regioneninfo:eu-repo/semantics/openAccessIsing ModelMean-field ApproximationPhenomenological ApproachRelaxation TimeMagnetic Dispersion MaximaArticle2461303131310.16984/saufenbilder.780082
