<p>A magneto-resistance device comprising a stacked structure, said stacked structure comprising a non-conducting substrate having a surface on which a multilayer structure is provided, the surface being furnished with a plurality of grooves which are substantially mutually parallel, each groove comprising a first face and a second face, all first faces being substantially planar and mutually parallel, the constituent layers of the multilayer structure being provided in a stack upon each said first face in such a manner as to be parallel thereto, the thickness of the stacks being such that each stack makes physical contact with each immediately neighbouring stack, the magneto-resistance effect of the multilayer structure being measurable by applying an electrical voltage gradient across the plane of the substrate in an in-plane direction substantially perpendicular to the grooves, thereby inducing a measurable flow of electrical current through the multilayer structure across the grooved surface of the substrate, the current thus flowing from one stack to the next in such a manner that, except in the vicinity of the region of electrical contact between immediately adjacent stacks, its direction is substantially perpendicular to the constituent layers of each stack. <IMAGE></p> |
