Abstract
In this paper Noise Enhanced Stability in magnetic systems is studied by both an Ising like model and a Preisach Arrhenius model as well as a Dynamic Preisach Model. It is shown that in one non equilibrium Ising systems Noise Enhanced Stability occurs and that Dynamic Preisach Model has the capability to predict the occurrence of NES in magnetic systems. On the contrary, in a Preisach Arhhenius model of a single quadrant magnetic material NES is not detected.
