摘要： Apparatus and methods are disclosed that enable writing data on, and reading data of, multi-state elements having greater than two states. The elements may be made of magnetoplastic and/or magnetoelastic materials, including, for example, magnetic shape- memory alloy or other materials that couple magnetic and crystallographic states. The writing process is preferably conducted through the application of a magnetic field and/or a mechanical action. The reading process is preferably conducted through atomic-force microscopy, magnetic-force microscopy, spin-polarized electrons, magneto-optical Kerr effect, optical interferometry or other methods, or other methods/effects. The multifunctionality (crystallographic, magnetic, and shape states each representing a functionality) of the multi-state elements allows for simultaneous operations including read&write, sense&indicate, and sense&control. Embodiments of the invention may be used, for example, for storing, modifying, and accessing data for device, sensor, actuator, logic and memory applications. Embodiments may be particularly effective for non-volatile memory or other read&write, sense&indicate, and/or sense&control functions in computer or other applications; such simultaneous operation of two (or more) of said multiple functionalities open new pathways for miniaturization of devices.

摘要： A monolithically formed ferromagnetic thin-film memory is disclosed that has local shielding on at least two sides of selected magnetic storage elements. The local shielding preferably extends along the back and side surfaces of a word line and/or digital lines of a conventional magnetic memory. In this configuration, the local shielding not only may help reduce externally generated EMI, internally generated cross-talk and other unwanted fields in the magnetic bit region, but may also help enhance the desired magnetic fields in the bit region.

摘要： The electric resistance of a magnetic constriction (M1, M2) varies if the magnetic status of one of the constriction sides changes. This resistance variation may exceed 100 % at room temperature. The invention proposes to use this effect to detect the magnetic status of a small magnetic particle, M3, as a magnetic storage bit, which affects the magnetic status on one side of the constriction (M1 in fig. 2). The invention also proposes to read the magnetic status of a small particle, M3, by using the particle as one side of the constriction (fig. 3).

摘要： A reusable information recording material comprises a layer (10) of transparent plastics formed with dimples (16) on one side, a further plastics layer (34), having a magnetic coating (14), being bonded to the dimpled side of layer (10), with the magnetic coating (14) directly adjoining the layer (10), so that respective closed cavities are defined by the dimples (16) and the layer (34, 14). Each said cavity contains one or more indicator particles (18) in the form of permanent magnets, each indicator particle (18) being dark on the side thereof corresponding with one pole and light on the side thereof corresponding with the other pole. The indicator particles are visible from one side of the material and the arrangement is such that the orientation of each particle (18) mirrors closely the orientation of the magnetic field, due to the magnetic layer (14), in the immediate vicinity of the particle. Consequently the particles provide an accurate visual indication of the corresponding state of magnetisation of the magnetic layer (14) and therefore the particles (18) can be made to represent, in visible form, information recorded magnetically on the magnetic layer, and thus, for example can be made to display a text or graphics.
