Abstract:
A magnetoresistive device comprising:a substrate;a metal layer formed over said substrate provided with a groove having first and second angled walls, said first angled wall forming a terminus of a first portion of said metal layer and said second angled wall forming a terminus of a second portion of said metal layer;a first plurality of layers of materials that exhibit a magnetoresistive effect when exposed to a magnetic field and an electric current, said first plurality of layers being formed along said first angled wall;a second plurality of layers of materials that exhibit said magnetoresistive effect when exposed to said magnetic field and said electric current, said second plurality of layers being formed along said second angled wall; anda conductive element that lies between and is in electrical and physical contact with said first and second plurality of layers, whereby when an electric current flows through one of said first and second portions of said metal layer, at least a component of said electric current flows approximately perpendicularly to said first and second plurality of layers and through the other of said first and second portions of said metal layer.
