Abstract

PROCEDE DE PREPARATION D'UN CORPS MAGNETIQUEMENT ANISOTROPIQUE A PARTIR D'UN SYSTEME D'ALLIAGES DU TYPE A DECOMPOSITION SPINODALE DANS UN CHAMP MAGNETIQUE. ON ETABLIT UNE FORMULE, EXPRIMEE EN FONCTION DE LA TEMPERATURE ET DE LA COMPOSITION, POUR L'ENERGIE LIBRE TOTALE DU SYSTEME D'ALLIAGE, ON CALCULE LA SPINODALE DU SYSTEME D'ALLIAGES A PARTIR DE CETTE FORMULE EN OBTENANT LE POINT DE DISPARITION DE LA DERIVEESECONDE DE CETTE ENERGIE POUR OBTENIR UNE PREMIERE COMPOSANTE SPINODALE APPLICABLE PARALLELEMENT A LA DIRECTION DU CHAMP MAGNETIQUE ET UNE DEUXIEME COMPOSANTE SPINODALE APPLICABLE PERPENDICULAIREMENT A LA DIRECTION DU CHAMP, ON TRACE SOUS FORME DE COURBES CES COMPOSANTES SPINODALES AVEC UNE COURBE DES TEMPERATURES DE CURIE DU SYSTEME D'ALLIAGES DANS UN DIAGRAMME DE PHASES ET ON TRAITE THERMOMAGNETIQUEMENT LE SYSTEME D'ALLIAGES A L'INTERIEUR DE LA ZONE DELIMITEE PAR LA PREMIERE ET PAR LA DEUXIEME COURBE SPINODALE EN LIAISON AVEC LA COURBE DES TEMPERATURES DE CURIE.
