Abstract

Atomic structures of cobalt-aluminum-oxygen nano-granular films prepared by reactive rf-sputtering from CoAl alloys in oxygen gas were investigated. This was done to clarify the atomic structures of the films and the interfacial layers in relation with their magnetic properties and tunnel magneto-resistance (TMR). The TMR was analyzed in terms of the Coulomb blockade and spin dependent tunneling.
