Abstract

Contribution of thermal energy, has been included in the micromagnetic simulation of laminated antiferromagnetically coupled (LAC) media. The antiferromagnetic coupling constant, J, required to obtain M _rt reduction in the existing simulation studies (T = 0 K) of LAC media is much higher than the experimental values. In this letter, we describe some experimental results, which point out that the contribution of thermal energy in M _rt reduction is significant. Consequently, we find that the values of J and the reversal fields are comparable to the experimental results, when thermal energy (T = 300 K) is included in the simulation.
