Magnetic stochastic resonance in systems described by dynamic Preisach model

Abstract

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