Abstract
A magnetoresistance-effect sensor for use in a magnetic domain detector for reading data recorded on magnetic tapes or in magnetic bubble memories mainly consists of a layer of semiconductor material which carries a layer of ferrimagnetic material on one face and at least one pair of electrodes disposed along an axis OX on the other face, the layer of ferrimagnetic material being placed in proximity to the magnetic data carrier. A magnetic data item thus induces a magnetic field in the layer of semiconductor material in a direction OY perpendicular to the axis OX of the pair of electrodes.
