Abstract
Kinetic Ising models have been used to study magnetization switching due to sudden field reversal in nanoscale ferromagnets. Work based on droplet theory for the decay of metastable phases has shown the existence of a size dependent spinodal field which separates the deterministic and stochastic decay regimes. The above works have recently been extended to study the effects of an oscillating field on the magnetization response of a nearest-neighbor kinetic Ising model. Here we present fits to the data for the frequency dependence of the distributions for the hysteresis loop area and for the residence-time distributions. The residence-time distributions indicate the presence of stochastic resonance.
