Abstract
PURPOSE: To enable to reduce a bias magnetic field component, by overlapping a bubble chip having a bubble magnetic domain drive conductive layer on the bubble material to a magnetic field compensating conductor layer on a substrate via an isolation gap, and flowing a current toward reverse direction to both the conductor layers.
CONSTITUTION: A bubble magnetic domain storage material 1 on the substrate material 2, and bubble chips having bubble magnetic domain drive conductor layer 31 on it, are mounted on the support base 6 having the magnetic field compensation conductor layer 35 with the same width substantially as the conductor layer 31 via a suitable isolation gap 36, so that conductor layers 31, 35 are overlapped. The parts 37, 38 corresponding to the current terminal of the conductor layer 35 are divided with electric isolation, the part 38 is connected to the conductor layer 31 via the conductor 40, and the conductor layers 31, 35 are electrically connected at the opposing side with the current terminal so that reverse current can flow to both the conductor layers. Thus, the bias magnetic field component caused in the bubble material 1 is cancelled with the magnetic field from the conductor layers 31, 35, allowing to obtain effective region for the drive of bubble magnetic domain almost at the entire area of chips.
