Sensor substrate and the sensor element which is suitable for performing the method as well as the sensor element or system sensor elements magnetization how to set the bias layer of a magnetoresistive sensor element, has been processed it accordingly

摘要

(57) At least [Abstract] and bias layers one and antiferromagnetically coupled to the both layers are arranged with the magnetic flux guide layer one, between them at least AAF system comprising a tie layer one (Artificial is a part of the antiferromagnetic system), the magnetization setting method of the bias layer one, the steps of heating or cooling the sensor element or below the temperature above a predetermined a), a and b, at least a magneto-resistive sensor element) and includes the steps of providing a setting field and during cooling or heating / or after a process of setting off the magnetic field after a predetermined time c), the process returns to the starting temperature d) temperature.
