Magnetic bubble element
专利汇可以提供Magnetic bubble element专利检索，专利查询，专利分析的服务。并且PURPOSE: To remarkably decrease the pulse current value required for the magnetic bubble control, by providing the notch groove having narrower width than that of the inside of the conductor loop so that the end of soft ferromagnetic substance layer notch is projected in eaves shape internal the loop.
CONSTITUTION: In the magnetic bubble replicate circuit, at the side present in the loop 2 of the transfer element chip 1 linked to the conductor loop 2 magnetically, the notch groove 100 having narrower width g than that of the inside of the loop 2 is provided, and from the both ends of the notch groove 100, the soft ferromagnetic substance layer notch ends 101a and 101b are projected in eaves shape in the loop exceeding the conductor pattern of the loop 2. With this constitution, when power is applied to the loop 2, magnetic field is caused around the conductors, causing strong S pole at the place where the center of the bubble 30 opposes to the upper surface at the lower ends of the ends 101a and 101b. The bubble 30 is relinguished into being sectioned to two parts. The operation current in this case is 30 to 50 mA(conventionally 60 to 100 mA) and the current value required for the control of sectioning the magnetic bubble can remarkably be reduced.
