Abstract :
The influence of the domain-wall size distribution on the wall component of the initial magnetic susceptibility has been considered. The basic consideration has been carried out on a model of magnetic material composed of spheres. Examples imitating the cases occuring in reality are given. It is inferred that the susceptibility depends strongly on the type and parameters of grain size distribution and on the number of walls inside the grain.
