Abstract

The transverse susceptibility (TS) signal of interacting magnetic systems with volume and anisotropy fields distribution was presented. The temperature dependence of TS was studied using the stochastic Landau-Lifshitz-Gilbert equation. Temperature has affected the oscillation of the moment and the magnitude of the phase shifts. These results were important to understand more accurately the physical sources of real and imaginary parts of TS that would provide information for the dynamics of the magnetic moments in modern recording media.
