Abstract
The present invention concerns in a first aspect a spin-valve structure having a first and a second free ferromagnetic layer and a spacer layer positioned between the first and second free ferromagnetic layer, and wherein the first free ferromagnetic layer is positioned on a substrate. In a preferred embodiment of the invention, the first free ferromagnetic layer is in direct contact with the surface of the substrate.
Claims60
A spin-valve structure comprising a first free ferromagnetic layer and a second free ferromagnetic layer and a spacer layer positioned between said first and second free ferromagnetic layers, wherein said first free ferromagnetic layer is positioned on a conducting substrate with an insulating barrier layer therebetween.
A spin-valve structure comprising a first free ferromagnetic layer and a second free ferromagnetic layer and a spacer layer positioned between said first and second free ferromagnetic layers, wherein said first free ferromagnetic layer is positioned on a substrate, said substrate having a lattice structure, said first free ferromagnetic layer having a lattice structure being influenced by the lattice structure of said substrate.
A spin-valve structure comprising a first free ferromagnetic layer and a second free ferromagnetic layer -and third layer positioned between said first and second free ferromagnetic layers, wherein said third layer comprises a layer selected from the group consisting of an antiferromagnetic layer, a metal layer, a semimetal layer and a conductive semiconductor layer, and wherein said first free ferromagnetic layer is positioned on a substrate forming an electrical barrier with a ferromagnetic layer being deposited thereon.
A method for producing a spin-valve structure, comprising electrodepositing said spin-valve structure on a substrate.
