Abstract :
The analysis of an artificial medium has led to a new type of Preisach model where the variance of the interaction field is a function of the magnetization. The ideal particles of this medium have no reversible magnetization and only interact magnetostatically with their neighbors. In this model, the line separating the positively and the negatively magnetized regions of the Preisach plane is not a staircase
