Correlation effects and magnetization processes in hard-drawn iron-nickel alloys

The problem of the magnetic anomalies of some hard-drawn iron-nickel alloys is considered, taking into account the effect of the irreversible jumps of the Bloch walls during magnetization. The effects of the correlation between walls are discussed in relation to the change of the mean area of the walls under different physical conditions. It is shown that the model of the coercive force involving the theory of the homogeneous random functions may be used.
