摘要： A magnetoresistive sensor comprising first and second magnetoresistive elements is disclosed. Each magnetoresistive element is coupled at a respective first end to a common ground terminal and comprises one or more magnetoresistive segments, each overlying a corresponding segment of an excitation coil. The resistance of the magnetoresistive segments in each of the first and second magnetoresistive elements is the same and the resistance of the segments of the excitation coil corresponding to the first magnetoresistive element is the same as the resistance of the segments of the excitation coil corresponding to the second magnetoresistive element.

摘要： An AMR sensor, comprises at least first and second AMR sensor elements to which opposite bias fields are applied. The first and second AMR sensor element outputs are combined to derive a sensor response which is substantially anti-symmetric in the region close to zero external magnetic field. This arrangement shifts the zero detection point of the AMR sensor elements away from a maximum of the response curve, so that sensitivity in proximity to a zero input field is obtained. To overcome the problem that the response is not anti-symmetric, the signals from (at least) two sensor elements are combined.

摘要： A thin-film bulk acoustic wave (BAW) resonator, such as SBAR or FBAR, for use in RF selectivity filters operating at frequencies of the order of 1 GHz. The BAW resonator comprises a piezoelectric layer (14) having first and second surfaces on opposing sides, a first electrode (16) extending over the first surface, and a second electrode (12) extending over the second surface, the extent of the area of overlap (R1) of the first and second electrodes determining the region of excitation of the fundamental thickness extensional (TE) mode of the resonator. The insertion loss to the resonator is reduced by providing a dielectric material (18) in the same layer as the first electrode (16) and surrounding that electrode. The material constituting the dielectric material (18) has a different mass, typically between 5% and 15%, from the material comprising the first electrode (16) it surrounds. The mass of the dielectric material (18) can be lower or higher than the mass of the first electrode (16). Planarisation of the dielectric material (18) enhances the performance of the device.

摘要： The invention relates to a read only magnetic information carrier (1b, 1c, 1d) comprising a substrate (2), an information layer (3) and a stabilizing layer (15a, 15b). The information layer (3) comprises a pattern of magnetic bits (4) of magnetic material wherein the pattern of magnetic bits (4) constitutes an array of bit locations. The presence or absence of the magnetic material at a bit location represents a value of the bit location by a magnetic field (5) having a predetermined magnetization direction (6). The stabilizing layer (15a, 15b) is arranged between the substrate (2) and the information layer (3) and comprises hard magnetic material (8, 9) which is magnetically coupled to the magnetic material of the magnetic bit (4). The magnetically coupled hard magnetic material (8, 9) provides the predetermined magnetization direction (6) of the magnetic field (5). The magnetic coupling between the hard magnetic material (8, 9) and the magnetic bits (4) prevents the predetermined magnetization direction (6) of the magnetized material of the magnetic bits (4) to change, which improves the thermal stability of the magnetic bits (4).

摘要： The invention relates to a method of manufacturing a device (10) comprising a layer (12) having a pattern of disjunct portions (14) of magnetic material (18) generating a corresponding pattern of local magnetic fields (2). The magnetic material (18) is constituted of particles (22) dispersed in a solid substance (24). The particles are magnetically stable and substantially aligned for generating the local magnetic fields (2). The method comprises the steps of: providing a substance (32) having the particles (22) dispersed in the substance (32), the substance (32) having a viscosity for allowing the particles (22) to move in the substance (32), creating the pattern of disjunct portions (14) of the substance (32) in the layer (12) of the device (10), applying an external magnetic field (50) for substantially aligning the particles (22) in the disjunct portions (14) of the substance (32), and solidifying the substance (32) for obtaining the solid substance (24). The benefit of this method is that instead of changing the magnetization inside the particles (22), the particles (22) are moved, typically rotated, to be aligned to the externally applied magnetic field (50). Subsequent solidification of the substance (32) fixes the aligned magnetically stable particles (22) inside the solid substance (24) which results in a permanently magnetized magnetic material (18).
