Abstract

a. Alliage pour la réalisation d'un élément magnétorésistant, composé d'un mélange de nickel et de cobalt de façon que le rapport entre les atomes des nickel et les atomes de cobalt soit essentiellement dans la plage 40/60 ... 60/40. b. Alliage caractérisé en ce qu'il présente une phase ordonnée avec une soustructure.
