Abstract (en)

The present invention concerns a preparation process of an oriented and textured magnetic body, comprising the following steps:   a) preparing a composition at a temperature such that it comprises crystallites of the body in the presence of a liquid,   b) subjecting the composition to a magnetic force producing a sedimentation of the crystallites,   c) cooling, in the presence of the magnetic force, while applying a temperature gradient appropriate for promoting the development of a desired texture in the sedimentation zone.
