Abstract: An external means for supplying a bias field of a polarity to contract single wall domains employed to insure the stability of single wall domains in a layer of a host magnetic material has been found to be unnecessary if a surface layer of the host material is prepared so that the surface is permanently magnetized normal to the plane of the host layer and exchangecoupled to the body of that layer.

Abstract: Magnetic garnet compositions grown by liquid phase epitaxy have appropriate magnetic properties for use in bubble domain devices - a class of magnetic devices in which information is represented by enclosed domain regions of polarity opposite to that of immediately surrounding material. Critical selection of compositions, all containing mixed rare earth cations, as well as careful choice of processing conditions yield films which are both uniform in composition and dimension, as well as lacking in hillock formation and other surface irregularities.

Abstract: A number of geometries are disclosed for magnetoresistance elements compatible with fine-grained, field-access, single wall domain arrangements that render the elements insensitive to the rotating in-plane magnetic field which moves domains in such arrangements.

CPC classification number: G11C19/0883
Abstract: Transfer of a single wall domain from one channel to another is achieved by blocking the path of a domain to its next normal position to a manner to create a temporary path along which the blocked domain adjusts its shape for movement to an alternate position to an alternate channel. A pulse on a properly disposed electrical conductor when formed with permalloy produces the desired operation.

CPC classification number: G01R33/09 , G11C19/0866
Abstract: An enhanced output signal is provided by the coupling of a magnetic bubble to a magnetoresistance detector element when the familiar rotating in-plane drive field is set at an amplitude such that the presence of a bubble results in a change in frequency in signal exhibited by the detector element due to the in-plane field. The largest signals yet achieved resulted from an integrated expansion detector, guard rail arrangement with a meandering magnetoresistance element when operated in this manner.

CPC classification number: G11C19/0841
Abstract: Domain propagation along a path defined by a straight line conductor is achieved by driving domains back and forth across the conductor against the edges of regions forbidden to the domains. By angling the edges of the regions with respect to the axis of the conductor and by offsetting those edges associated with one edge of the conductor with respect to those associated with the other, the back and forth motion is translated into movement along the axis.
Abstract translation: 通过由直线导体限定的路径的域传播是通过将导体横穿导体抵抗不被域阻挡的区域的边缘来回驱动来实现的。 通过相对于导体的轴线倾斜区域的边缘并且通过将与导体的一个边缘相关联的那些边缘相对于与另一个相关联的边缘偏移，来回运动被转换为沿着轴的运动。

Abstract: Single wall domains have been found to be movable in a host magnetic layer in the absence of a bias field and in the absence of sufficient coercivity in the host layer for maintaining the domain walls in fixed positions when drive fields terminate.
