Abstract
PURPOSE: To improve the magnetic field efficiency of a rotating magnetic field for bubble driving to make power loss and a calorific value small and the device small-size by using a conductive layer, which is formed directly on the magnetic bubble chip outside face by the evaporation method, etc., for a driving coil.
CONSTITUTION: Conductive layers 7 and 7' are formed as a Y coil throughout the outside face for the surface and the reverse face of magnetic bubble chip 3', where SiO2 insulating film 33 used for a spacer commonly, controlling conductor pattern 34 for a bubble generator, a replicator, etc., SiO2 insulating film 35, permalloy pattern 36 for a gate, a transfer path, a gate, a replicator, a detector, etc., and SiO2 surface protection film 37 are formed in order on magnetic thin film 32 formed on Gd.Ga.garnet single crystal 31 by the liquid-phase epi-taxial method, by the evaporation method, etc. On these layers 7 and 7', similar conductive layers 9 and 9' are formed through insulating films 8 and 8' such as SiO2 as an X coil orthogonal to the Y coil.
