    摘要： The invention relates to a flow chamber of a flow cytometer, wherein labeled cells are highly likely to be detected by means of a corresponding sensor. A medium comprising the magnetically labeled cells can flow through the flow chamber and the flow chamber comprises at least one sensor positioned on an inner surface of the flow chamber to detect the cells. The flow chamber further comprises a magnetic or magnetizable cell guiding device which can be positioned upstream of the sensor in the direction of flow and which is arranged and designed such that it guides the flowing, magnetically labeled cells directly across the sensor, thereby achieving that only a small percentage of labeled cells passes the sensor outside of its reach.

    摘要： A fabrication process and apparatus provide a high-performance magnetic field sensor (200) from two differential sensor configurations (201, 211) which require only two distinct pinning axes (206, 216) which are formed from a single reference layer (60) that is etched into high aspect ratio shapes (62, 63) with their long axes drawn with different orientations so that, upon treating the reference layer with a properly aligned orienting field (90) and then removing the orienting field, the high aspect ratio patterns provide a shape anisotropy that forces the magnetization of each patterned shape (62, 63) to relax along its respective desired axis. Upon heating and cooling, the ferromagnetic film is pinned in the different desired directions by one of 1) tailoring the intrinsic anisotropy of the reference layer during the depositing step, 2) forming a long axes of one of the patterned shapes (62, 63) at a non-orthogonal angle to the long axes of the other patterned shape (62, 63) when etched, or 3) applying a compensating field when pinning the reference layers.

    摘要： A GMR sensor stripe formed as a lamination of contiguous horizontal layers of substantially identical horizontal dimensions and having a free layer bias point that is stable with respect to hysteresis, comprising:
    a pinned layer having a magnetic moment and a coefficient of magnetostriction;
    a non-magnetic electrically conducting spacer layer formed on said pinned layer;
    a ferromagnetic free layer having a magnetic moment and a coefficient of magnetostriction, formed on said spacer layer; and
    a layer of insulating material surrounding and encapsulating said sensor stripe, said material producing an anisotropic compressive or tensile stress on said sensor, and wherein said layers have a width dimension and a length dimension that is greater than said width dimension producing, thereby a magnetic shape anisotropy; and wherein said ferromagnetic free layer acquires a stress induced magnetic anisotropy from the combination of said tensile or compressive stress and said coefficient of magnetostriction and wherein the magnetic moments of said pinned and free layers are aligned parallel to said length dimension when said sensor is in a quiescent state.
