PURPOSE:To obtain large detection outputs which are proportional to detection currents, by making an arrangement so that the direction of a magnetic field generated by the detection current in the area sorrounded by the winding paths of the electric current at the exit of bubbles of thick film type magnetic bubble detectors, may become the same as that of the bias magnetic field. CONSTITUTION:It is arranged that a detector current I' is passed through a magnetic bubble detector 3 along the direction shown by the arrow, and the direction of a magnetic field H'1 generated by the detection current I' in area 10 surrounded by the winding path of the electric current at an exit of bubbles 2 is set to become the same as the direction of the bias magnetic field HB. Magnetic bubbles are transferred from the exit alpha of the detector 3 to the entrance of the next transferring path, because another magnetc field H'2 generated at the outside of the path of the electric current is smaller than the magnetic field H'1 though the direction of the magnetic field H'2 is contray to the other. Therefore, a large detection output which is proportional to the detection current I' can be obtained. |
