MAGNETIC BUBLE ELEMENT

PURPOSE:To easily attain electric insulation between two layers and to decrease the total driving current, by forming a bubble propagation pattern of the two layers which are mutually insulated and partially duplicatedly arranged in a minute zigzag shape repeated with a prescribed period. CONSTITUTION:Apexes 56-63 of zigzag of the 1st conductor stripe 50 and the 2nd conductor stripe 51 are arranged at positions shifted by 1/4 period each. Through currents 52-55, the vicinity of the recessed points of the stripe 51 has a large current density and the vicinity of the projected points has a small current density, then a strong induced magnetic field is produced near the apexes inversely to a bias magnetic field 11 and a strong induced magnetic field is produced to the apexes in the same direction as the magneic field 11. Since the overlapped area of the stripes 50 and 51 is small, the electric insulation between both the layers is made easy and since the storage capacity can be increased and power can be conducted through the stripe layers, the total driving current can be reduced.
