Abstract:
1. A device comprising: a solid body having a surface; a magnetoresistive structure disposed in said body adjacent to said surface, said magnetoresistive structure extending a first amount in a first direction that is substantially parallel to said surface, extending a second amount in a second direction that is substantially perpendicular to said surface, and extending a third amount in a third direction that is perpendicular to said first and second directions, with said third amount being less than each of said first and second amounts; a first lead layer disposed in said body adjacent to said surface and made of material having a resistivity of less than 6×10 a second lead layer disposed in said body adjacent to said surface, separated from said first lead layer in said first direction and made of material having a resistivity of less than 6×10 first and second metal layers each adjoining the first lead layer, extending along the first portion and having an electrical resistivity greater than 6×10 wherein said first portion is separated from said first part by a distance that is substantially identical to that separating said second portion from said second part.
