Les microstructures des couches minces en alliage CoCr ont été étudiées par microscopie électronique à transmission transversale en se concentrant sur la région de croissance initiale de la couche magnétique cultivée sur des sous-couches non magnétiques. Une introduction au non magnétique hcp-Couche CoCrRu entre un hcp-Couche d'enregistrement CoCrPt et un hcp- ou un bcc-la sous-couche a amélioré la qualité cristallographique de la région de croissance initiale. Des distributions de composition nettes d'éléments d'alliage aux interfaces d'un milieu perpendiculaire CoCrPt/CoCrRu/CrTi et d'un milieu longitudinal CoCrPt/CoCrRu/CrTi ont été respectivement confirmées par spectroscopie de perte d'énergie électronique utilisant un faisceau d'électrons finement focalisé. La coercivité et l'équerrage des supports en couches minces ont été augmentés grâce à la réalisation d'une bonne hétéro-épitaxie entre le non magnétique et le magnétique. hcp-couches.

Abstract: Microstructures of CoCr-alloy thin film media were investigated by cross-sectional transmission electron microscopy focussing on the initial growth region of the magnetic layer grown on nonmagnetic underlayers. An introduction of nonmagnetic hcp-CoCrRu layer between an hcp-CoCrPt recording layer and an hcp- or a bcc-underlayer improved the crystallographic quality of the initial growth region. Sharp compositional distributions of alloying elements at the interfaces of a CoCrPt/CoCrRu/CrTi perpendicular medium and a CoCrPt/CoCrRu/CrTi longitudinal medium were respectively confirmed by electron energy loss spectroscopy employing a finely focussed electron beam. Coercivity and squareness of the thin film media increased by realizing good hetero-epitaxy between the nonmagnetic and the magnetic hcp-layers.
