Abstract:
A device for setting a fixed predetermined magnetization distribution in a bias layer of at least one magneto-resistive sensor element, the at least one sensor element including a thin-film structure situated on a substrate and having a giant magneto-resistive effect, the bias layer having a predetermined direction of orientation of magnetization, the device comprising:at least one electrically conducting conductor part;a positioning arrangement for positioning the at least one conductor part relative to the at least one magneto-resistive sensor element in a detachable manner; anda current carrying arrangement for carrying a predetermined current in the at least one conductor part to generate at least a portion of a magnetic field, the current carrying arrangement fixably setting the magnetization in the bias layer of a respective sensor element of the at least one magneto-resistive sensor element in the predetermined direction of the orientation.
