ABSTRACT:
A magnetoresistive sensor has at least one strip-shaped conductor that is formed from a magnetoresistive material and that is designed to determine its electrical resistance, which can be influenced by an external magnetic field, and/or to be acted on by an electric current. In order to construct a magnetoresistive sensor of this type in such a way that a further reduction in the hysteresis and an improved linearity are obtained, at least one screening strip is provided according to the invention that is disposed at least substantially parallel to and at a predetermined spacing from the conductor and is electrically separated from it.
