    摘要： A sensor for measuring a magnetic field includes a substrate, four magnetic elements arranged in a bridge configuration on the substrate, a first bridge portion. A first element and a second element are connected in series, a second bridge portion, and a third element and a fourth element are connected in series, being situated between a first contact and a second contact. The first bridge portion includes an electrical shunt resistor, which is arranged parallel to the first magnetic element of the bridge. In order to compensate for offset voltage and offset voltage drift in the output voltage of the bridge configuration, the temperature coefficient of the shunt resistor compensates for the variation of the temperature coefficients of the magnetic elements in the bridge.

    摘要： The invention relates to a method and a sensor device (100) for detecting particles (MP) that are bound to the binding surface (12) of a carrier (11). The sensor device (100) comprises a microscope (50) for imaging bound particles (MP) onto an image sensor (53). In order to increase the spatial resolution of the microscope(50), a displacement unit (60,70,80) is provided that can displace the carrier (11) relative to the image sensor (53). The distance of a bound particle (MP) from the binding surface (12) and/or its lateral displacement in reaction to forces can thus be determine with high accuracy. This allows to discriminate specific bindings of large magnetic particles (MP) that are bound to the binding surface (12) via smaller target particles from nonspecific direct bindings.

    摘要： A method of manufacturing a magnetic tunnel junction device, in which a stack (1) comprising two magnetic layers (3, 7) and a barrier layer (5) extending in between is formed. One of the magnetic layers is structured by means of etching, in which, during etching, a part of this layer is made thinner by removing material until a rest layer (7r) remains. This rest layer is passivated by chemical conversion. In the relevant method, it is prevented that the magnetic layer which is not to be structured is detrimentally influenced during structuring of the other magnetic layer.

    摘要： A method of orienting the axis of magnetization of a first magnetic element with respect to a second magnetic element uses a first element and a second element lying on a substrate. Each of the elements has a magnetic layer with an axis of magnetization. The method includes depositing a pattern of flux-concentrating material close to the first element and subsequently orienting the axis of magnetization of the first element in an applied magnetic field. The semi-finished article for measuring a magnetic field includes a substrate, a first magnetic element, a second magnetic element, a third magnetic element and a fourth magnetic element on the substrate in a bridge configuration. A first bridge portion is provided wherein the first element and the second element are electrically connected in series. A second bridge portion is provided wherein the third element and the fourth element are electrically connected in series.

    摘要： Magnetic field sensors and magnetic memories have at least two magnetoresistive bridge elements (A,B,C,D), wherein each magnetoresistive element comprises a free (F) and a pinned (P) ferromagnetic layer. The magnetization directions of pinned ferromagnetic layers are different for the two bridge elements. In the method, in a first deposition step, a first ferromagnetic layer of one of the two said elements is deposited, during which deposition a magnetic field is applied to pin the magnetization direction MP in the first ferromagnetic layer in a first direction. Then, in a second deposition step, a second ferromagnetic layer of the other of the two said elements is deposited, during which deposition a magnetic field is applied to pin the magnetization direction in the second ferromagnetic layer in a second direction different from, preferably opposite to, the magnetization direction in the first ferromagnetic layer.
