Abstract
MEMOIRE A DOMAINES EN FORME DE BULLE PRESENTANT LES AVANTAGES DES SYSTEMES A PROPAGATION DES BULLES SUR DES ELEMENTS CONTIGUS ET DES SYSTEMES A RESEAUX DE BULLES. UN ENSEMBLE DE DOMAINES A BULLES TEL QU'UN RESEAU EST DEPLACE LE LONG DE CONFIGURATIONS DE PROPAGATION A ELEMENTS CONTIGUS EN REPONSE A LA REORIENTATION D'UN CHAMP MAGNETIQUE DANS LE PLAN DU FILM DE BULLES. DES RANGEES ADJACENTES DE DOMAINES DANS L'ENSEMBLE SE DEPLACENT DANS DES SENS OPPOSES POUR FOURNIR DES BOUCLES D'EMMAGASINAGE INDIVIDUELLES A L'INTERIEUR DE L'ENSEMBLE. APPLICATION AUX MEMOIRES A BULLE MAGNETIQUE.
