Abstract

Abstract A magnetoresistive element of an insulating substrate, a first current conducting ferromagnetic metal film strip on said substrate and having a current carrying ability predominantly in one direction, a second current carrying ferromagnetic metal film strip on the substrate having a current carrying ability predominantly in a direction substantially perpendicular to the aforementioned direction, the ends of said strips being connected together, with a current input terminal connected to the opposed ends of the strips and an output terminal connected to the junction between the two strips.
