Abstract
PURPOSE: To realize a simple constitution for the bubble element which excels in the gap tolerance of the transfer pattern and is suited for the microprocessing by providing the stage error part to the bubble meterial magnetic film and then distributing the transfer pattern on the stage error part.
CONSTITUTION: Bubble-use magnetic film 1 featuring the single-axis anisotropy is grown by the liquid-phase epitaxial method onto single-crystalsubstrate 2 such as the Gd. Ga garnet or the like. In this case, part 11 of film 1 is formed thin with part 12 formed thick each, and stage error 13 is provided between 11 and 12. Then spacer layer 3 of SiO and the like is coated over film 1, and circular transfer pattern 4 is arranged in plural number on layer 3 to be positioned on error 13 and with the same space between. As a result, the potential of the magnetic field varies suddenly at stage error 13, and accordingly bubble 5 cannot intrude into thick film part 12 getting over the high potential part even though it receives the suction force from the suction pole piece of the transfer pattern, and thus has to stay at the low potential part.
