L'auteur analyse le contexte physique d'étude des mécanismes d'aimantation dans les matériaux magnétiques doux. On montre comment la théorie proposée par l'auteur et basée sur le concept de dimension de parois a permis d'aboutir dans le cas des matériaux polycristallins, où la dimension de la paroi est déterminée par les joints des grains, à l'établissement d'un cycle universel (intercomposition) d'hystérésis. Un tel cycle, obtenu à partir de mesures sur des ferrites et des grenats, est présenté.The author analyzes the physical context of the magnetization mechanism investigations in the soft magnetic materials. It is shown how a universal (intercomposition) hysteresis loop can be established on the basis of the domain wall size theory, pre...
