Abstract

MICRO-PLAQUETTE DE DOMAINES EN FORME DE BULLES AYANT DEUX NIVEAUX DE METALLURGIE FABRIQUES AU COURS DE LA MEME ETAPE DE MASQUAGE ET COMPRENANT UN GENERATEUR DE BULLE G. LE GENERATEUR COMPREND UN ELEMENT PLAT D QUI MAINTIENT UN DOMAINE-GERME PENDANT LA REORIENTATION D'UN CHAMP DE COMMANDE MAGNETIQUE, ET UN CONDUCTEUR C PLACE SUR UN BORD DE L'ELEMENT D. UN COURANT DANS LE CONDUCTEUR EST UTILISE POUR REALISER UNE OPERATION DE SECTIONNEMENT CREANT AINSI UN NOUVEAU DOMAINE A PARTIR DU DOMAINE-GERME ALLONGE. APPLICATION AUX MEMOIRES A BULLES MAGNETIQUES.
