摘要： The layer arrangement (5) has a reference layer (6) deposited on a substrate. This has a magnetization (m2) not affected by the direction of an external field (B). On top of this is a non-magnetic conductive layer (4) topped by a detector layer (2). The latter has a magnetization (m1) always in parallel to the external field. In plan view the layer arrangement forms a meander.

摘要： The device i.e. sheath-type glowplug (1) has a rod-shaped heating element (2) protruding partially from housing (3). A rigid body (6) e.g. sleeve shaped electrically conductive rigid body, is indirectly supported at the housing such that the body indirectly stays in connection with the heating element. A layer system (7) with a piezoelectric layer i.e. active electromechanical transducer element, is provided on the rigid body such that impact of the rigid body indirectly limits mechanical voltage fluctuation in the layer, where the impact occurs depending on pressure prevailing in the chamber.

摘要： A magnetically sensitive component (30), in particular a sensor element, with at least two magnetoresistive layer systems (20) produced in regions on a substrate (10), is proposed. Here each of the layer systems (20) has at least one reference layer (2, 2'), at least one intermediate layer (3) adjacent to the reference layer (2, 2') and at least one detection layer (1) adjacent to the intermediate layer (3), and are connected as bridge resistors (R 2 , R 4 ) in an electrical circuit in the form of a Wheatstone bridge (21). Moreover, at least one of the reference layers (2, 2') has at least one magnetoresistive layer system (20), at least one first partial layer (2a, 2a') and at least one second partial layer (2b, 2b'), wherein the first partial layer (2a, 2a') exhibits a magnetisation (m 2 ) and the second partial layer is an antiferromagnetic partial layer (2b, 2b'). The magnetically sensitive component (30) is especially suitable for contactless and largely temperature-independent and offset-free recording of speeds and angles based on the GMR or TMR effect. In this connection it can also be used in the presence of strong external magnetic fields.

摘要： Disclosed is a method for adjusting magnetization, especially local modifications, in the resulting magnification (m2) in a layered arrangement (2) with a ferromagnetic layer (2a) and an adjacent antiferromagnetic layer (2b). The antiferromagnetic layer (2b) is initially heated, at least partially, to above a threshold temperature (Tb), especially with the aid of a laser. Above said temperature, the influence of said area on the resulting direction of magnetization (m2) of the adjacent area (5, 6, 8, 9) of the ferromagnetic layer (2a) disappears substantially. At least the area (5,6,8,9) of the ferromagnetic layer (2a) adjacent to the heated area of the antimagnetic layer (2b) is exposed to an external magnetic field (H) of a given direction and the antiferromagnetic layer (2b) is finally cooled to below the threshold temperature (Tb). The inventive method is particularly suitable for production of a magnetoresistive layered system working according to the spin-valve principle with partially different directions of magnetization (m2) which are connected in the form of Wheatstone bridges.

摘要： A magnetically sensitive component 30 has at least two magnetoresistive layer systems 20 that exhibit a GMR or TMR effect. Each layer system 20 comprises a reference layer 2, 2', a detection layer 1 and an intermediate layer 3. The reference layer comprises a magnetic layer 2a and an antiferromagnetic layer 2b. To manufacture the magnetically sensitive component a sacrificial layer (12, fig 4a) is deposited on the intermediate layer 3, and the reference layer 2 of the first layer system is deposited at least in a region not occupied by the sacrificial layer. The sacrificial layer is then removed, for example in a lift off process, and the reference layer 2' of the second layer system is deposited in regions previously occupied by the sacrificial layer. The magnetic layers 2a, 2a' of the reference layers are given opposite directions of magnetisation in the two layer systems, as indicated by the arrows. This is done by the application of an external field H during the manufacturing process.

摘要： The manufacturing system incorporates a hot stamp (5) which may be electrically heated. It has a disk (12) with an array of square or rectangular projections (13) on its underside. The flat undersides of the projections approach or contact meander-shaped structures (14) in a substrate (10) for a magnetoresistive layer (11). The projections may be from 1 mm to 5 mm high, with a surface area of 0.5 to 2.0 square mm. The affected areas may be heated to over 220 degrees C.
