IPC: G11C11/14
Filed: 1981-01-19
Abstract: PURPOSE:To expand bubbles easily by only a bubble transfer driving current, by providing a one-turn coiled conductor sheet layer, opposed through an insulating layer, on a conductor layer so that it surrounds a bubble expansion detection part. CONSTITUTION:A magnetic bubble element provided with conductor layers 2 and 4 having pattern holes 9 and 10 on a magnetic thin film 1 is provided with a one-turn coiled conductor sheet layer 30 opposed through an insulating layer 3 on the conductor layer 4 so that it surrounds a bubble expansion detection part 8. Electricity is fet to this sheet layer 30 to decrease a bias magnetic field near the bubble expansion detection part 8, making magnetic bubbles easy to expand. For example electricity feeding from the electrode terminal 41 to the 42 of the 3rd conductor layer 30 is performed to produce an induced magnetic field as shown by an arrow 44, and this magnetic field 44 weakens the bias magnetic field 6 to weaken the bias magnetic field at a recessed pattern 40, so that bubbles become easy to expand in this area.
