✦ Synopsis

A magnetization process which may contribute to the .initial permeability P0 of ~intered NiZn ferrites is ascribed to the displacement oI mobile walls.Walldisplacements are also responsible for the dependence of/2 0 on the angle between the directions of magnetization and of a.c. field demagnetization.

The reversible influence of stress on P0 can be accounted for by considering only simultaneous spin rotations. The influence of an anisotropic spin distribution on P0 in the absence of external stress is a strong argument for the assumption that rotation is the preponderant initial magnetization process for these porous ferrites.
