    Abstract: A self-bias sensor including a current source, a resistance measuring device and a sensor element sensitive to a magnetic field to be measured. The sensor element receives from the current source a current which creates a self-biasing field. The sensor element includes a first ferromagnetic layer having a magnetization direction which is sensitive to the magnetic field and when not subject to the magnetic field, and is oriented by the self-biasing field in a direction perpendicular to a longitudinal direction of the sensor element; a second ferromagnetic layer disposed between a first and second conductive layer, where the second ferromagnetic layer has a magnetization which is blocked and directed in the longitudinal direction; and a third ferromagnetic layer which is disposed on the second conductive layer and has a magnetization direction which is sensitive to the magnetic field and, when not subject to the magnetic field, is oriented by the self-biasing field in a second direction perpendicular to the longitudinal direction and substantially of an opposite sense to the magnetization of the first ferromagnetic layer.

    Abstract: A magnetoresistive component and transducer for use therewith. The magnetoresistive component has a multilayer-type magnetoresistive strip bent in accordance with a repeated geometrical pattern (7a,7b). The pattern has at least one series of substantially parallel sections (7a,7b) for reducing the demagnetizing fields. The magnetoresistive strip (2) is formed from a stack (13) of magnetic metallic material layers (14) separated by non-magnetic metallic material layers (15). The magnetoresistive component is applicable to a transducer for reading information recorded in magnetic form or for detecting weak magnetic fields.
