Abstract

In this paper, dynamic Preisach model is applied to investigate magnetic stochastic resonance. It is shown that magnetic systemsdescribed by dynamic Preisach model presents magnetic stochastic resonance. The resonance in the power amplification disappears if thefrequency of the input signal is greater than characteristic frequency of the system introduced by dynamic Preisach model and theresonance in signal to noise ratio is strongly reduced under the same condition. Finally, frequency and phase locking phenomenon isdetected under resonance condition.
