Abstract :
A model based on optimal reversal path of stochastic dynamics of magnetization is used to characterize thermal reversal behavior of magnetic grains under arbitrary pulse field below medium coercivity. The effects of pulse field duration, width, magnitude and angular effects on magnetic grain thermal switching behavior is studied using the model.
