摘要： A multilayer magnetic sheet comprises ten or more layers of magnetic strips each formed in a band shape with a short side and a long side. The magnetic strips are aligned and arranged in a plate shape in each of the layers such that the long sides of the magnetic strips are adjacent to each other. The layers comprise first layers, in which the long sides of the adjacent magnetic strips overlap, and second layers, in which the long sides of the adjacent magnetic strips do not overlap. The first layers comprise at least two stacked layers. A position of the long side in one layer included in the second layers is separated from a position of the long side in another layer included in the second layers by 0.5 mm or more in a direction in which the short side extends.

摘要： The invention provides a novel magnetic material having an epitaxially grown single crystalline film of spinel ferrite such as hematite and magnetite as a magnetic layer formed on a substrate. In place of a single crystal substrate of, e.g., magnesium oxide, on which an epitaxial spinel ferrite film is directly grown, the spinel ferrite film in the inventive magnetic material is epitaxially grown on a mica plate as the substrate with intervention of a buffer layer which is a single crystalline thin film of magnesium oxide epitaxially grown on the substrate surface. The thus prepared magnetic material can be used in magnetic devices by virtue of the inexpensiveness and high magnetic properties.

摘要： This application discloses a method of recognizing and/or locating preselected categories of articles, which comprises applying to the articles a plurality of magnetic elements in predetermined associations (e.g. with predetermined numbers of magnetic elements and with predetermined spacings between said elements), whereby when the articles are caused to move relative to a predetermined interrogating magnetic field, each particular association of magnetic elements gives rise to a magnetic signature whereby the article or category of article carrying each of the predetermined associations can be recognized and/or located. A series of tags or markers for use in such a method, as well as a system for determining the location and/or identity of an article within an article conveying network, are also disclosed. Typically, one of such a series of tags will have a plurality of magnetic elements (2, 3, 4, 5, 6, 7, 8, 9, 10) whose individual magnetic characteristics, and whose number, shape, location and orientation on a substrate, determine the individual character of the magnetic response of the tag. By varying one or more of these parameters, a large family of magnetically individually recognizable tags can be generated.
