At least one magnetically hard layer is integrated in the layer system, at least in certain areas, applying a magnetic field at least in the area of a boundary surface between the magnetic layers and the intermediate layer. The magnetoresistive layer system is suitable in particular for use in a GMR sensor element including coupled multilayers or in an AMR sensor element having a barberpole structure.

摘要： A method of adjusting or locally modifying the direction of magnetization of a ferromagnetic layer in a magnetoresistive layer system using a heat stamp is described, the ferromagnetic layer being stabilized over an antiferromagnetic layer. The antiferromagnetic layer is heated, using a heat stamp, over a threshold temperature, above which the influence of this layer on the direction of magnetization of the adjacent ferromagnetic layer disappears; subsequently, the ferromagnetic layer is exposed to an external magnetic field of a predefined direction, and finally the antiferromagnetic layer is cooled again below the threshold temperature. In addition, a heat stamp having a base body and a heatable stamp structure connected to the base body and matching the dimensions of or similar to the magnetoresistive layer system is described. The heat stamp and the method described are suitable in particular for manufacturing a magnetoresistive layer system operating by the spin valve principle, which has a plurality of magnetoresistive layer systems having at least partially different resulting directions of magnetization in the particular layers, the magnetoresistive layer systems being interconnected in the form of a Wheatstone bridge in particular.

摘要： A magnetoresistive sensor element is provided, having a magnetoresistive layer system which, in top view, is at least regionally striated. The sensor element operates on the basis of the GMR effect and is constructed according to the spin valve principle, the striated layer system featuring a reference layer having a direction of magnetization substantially uninfluenced by a direction of an outer magnetic field acting on it. During operation, the sensor element provides a measuring signal which changes as a function of a measurement angle between the component of the field strength of the outer magnetic field lying in the plane of the layer system, and the direction of magnetization, and from which this measurement angle is able to be ascertained. In addition, observed in a top view of the striated layer system, the angle between the direction of magnetization in the absence of the outer magnetic field and the longitudinal direction of the striated layer system is set in such a way that in response to an influence of the outer magnetic field having a defined field strength, which is selected from a predefined work interval, the angle error of the layer system, as a function of this angle and the field strength, is minimal.

摘要： A device for measuring an angle and/or the torque acting on a rotatable body is proposed according to the invention, whereby the rotational angle is detected by means of magnetic or optical sensors. In particular, in a preferred exemplary embodiment, two devices (7, 8) are proposed, each of which comprises two optically readable code tracks. The two code tracks (1a, 1b or 2a, 2b) on one device (7 or 8) are similar in design and are offset in relation to each other, so that associated sensors (4) output a digital signal. The rotational angle is calculated based on the lag between the two digital signals. In a further embodiment it is provided that a torsion element (5) having a known torsional stiffness is situated between the two devices (7, 8). Torque transferred by the rotatable body (3) can also be calculated therefore from the angular difference of the two devices 7, 8. The device is used preferably in the steering axle of a motor vehicle.

摘要： A sensor element is described having a substrate and a first magnetoresistive layered assemblage having at least locally a first strip having a first strip width, and a second magnetoresistive layered assemblage having at least locally a second strip having a second strip width different from the first strip width. A gradiometer assemblage is described having at least two gradiometer bridges which have magnetoresistive, at least locally strip-shaped, layered assemblages of this kind, the strips in the individual gradiometer bridges being of different widths. This sensor element or gradiometer assemblage is suitable in particular for measuring magnetic field gradients over at least five orders of magnitude at magnetic field strengths from 1 μT to 30 mT, in particular from 1 μT to 10 mT. A method for measuring magnetic field gradients using a sensor element or a gradiometer assemblage of this kind is described, an overall measurement range exceeding the measurement range of an individual layered assemblage being obtained by way of a different setting of the width of the strips.
