摘要： A low-anisotropy magnetic material is exchange coupled in juxtaposition with a compatible body of high-anisotropy magnetic material so that a reduced external magnetic field is required for the nucleation and passage of a domain wall from the low-anisotropy material, through the interface between the low- and high-anisotropy materials, and into the high-anisotropy material. The propagation of the domain wall continues to affect a reversal in the direction of magnetization in the high-anisotropy material.

摘要： A nonmagnetic substrate is shown having a magnetic film that has been separated into a grid-like pattern of spaces to form quadrilateral magnetic elements. The spaces are filled with conductors arranged generally in X and Y directions. Each quadrilaterally shaped magnetic post element has a first and second region of low anisotropy material compared to the high anisotropy material of the magnetic film. The first regions of low anisotropy material are located in one corner of the quadrilaterally shaped post elements while the second regions are located in the corner opposite the first regions. Alternate columns of magnetic post elements have the first and second regions of low anisotropy material in opposite corners defined by a first diagonal, while the remaining columns have the low anisotropy material in corners defined by the second diagonal. This arrangement permits redundant switching of each magnetic post element.
摘要翻译：非磁性衬底被示出具有已被分离成网格状空间的磁性膜以形成四边形磁性元件。这些空间填充有通常在X和Y方向布置的导体。与磁性膜的高各向异性材料相比，每个四边形磁性柱元件具有低各向异性材料的第一和第二区域。低各向异性材料的第一区域位于四边形柱状元件的一个角部，而第二区域位于与第一区域相对的拐角处。磁柱元件的备用列具有由第一对角线限定的相对角中的低各向异性材料的第一和第二区域，而剩余的柱在由第二对角线限定的拐角中具有低各向异性材料。这种布置允许每个磁性柱元件的冗余切换。

摘要： An improved conductive grid for a magneto-optic display is shown having individual magnetic and transparent post elements separated from one another by an orthogonal grid-like pattern. Conductors are deposited in each vertical separation and every other horizontal separation. A first region of low anisotropy material compared to the high anisotropy material of each post element is located in close proximity to the intersection of each vertical and horizontal conductor.

摘要： A magnetic bubble domain system including a planar layer of magnetic material in which magnetic bubble domains can be propagated; and first and second bubble domain guide structure coupled to the layer and defining respective first and second bubble propagation paths for guiding the movement of bubbles in the layer in response to a cyclical change in the orientation of a reorienting magnetic field within the plane of the layer. A transfer bubble domain guide structure coupled to the layer is also provided for transferring bubble domains between the first and the second propagation paths responsive to a reverse in direction of the reorienting magnetic field. The transfer path is substantially the same as one of the directions of the crystallographic axes of the planar layer.
