Firstly, the rate equations are linearized. Then, these are solved in the presence of an oscillating external magnetic field. From the real and imaginary parts of ? , the magnetic dispersion and absorption factors are found. Temperature dependence of these quantities in the ferromagnetic and paramagnetic phase regions (as well as their critical properties) are presented. Finally, the theoretical results are compared with those obtained using irreversible thermodynamicseninfo:eu-repo/semantics/closedAccessSpin˗1 Ising ModelDynamic SusceptibilityPath Probability MethodConference Object115
