摘要：

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(r)t 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(r)t 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.
