摘要： A microdynode electron multiplier provides numerous microchannels extending parallel to one another through a layered structure incorporating insulating spacer layers and dynode layers which either incorporate a conductive electrode layer or are contiguous with a conductive electrode layer. The dynode layers include materials with high electron emissivity. The dynode layers can be biased to different electrical potentials to provide a potential gradient along the length of each microchannel. Multi-stage electron multiplication provides high gain. The device desirably is formed as a monolithic, sealed structure with a cathode structure such as a photocathode and an anode structure. The device can provide a multi pixel imaging device of extremely high sensitivity and resolution.

摘要： A static magnetic memory includes a layer having a plurality of vertically oriented and shape-anisotropic elongated ferromagnetic particles. A plurality of writing conductors are adjacent the layer, and the conductors selectively apply magnetic fields to selected regions of the layer by directing electrical current to magnetize the particles in an up or down direction. Static reading means detect the direction of magnetization. The particles may include a soft magnet portion and a hard magnet portion. In another preferred embodiment, a material and a method of making same includes providing a matrix full of elongated holes, depositing a first magnetic material having a first coercivity into the holes, and then depositing a second magnetic material having a second coercivity into the holes to form a composite elongated particle in each hole.

摘要： A magnetically shape-anisotropic material is made by providing a matrix with a plurality of elongated holes, and depositing first and second magnetic materials in each hole so as to form elongated particles including the first material adjacent one end and the second material adjacent the opposite end. One of the materials is a magnetically soft material having relatively low coercivity whereas the other material is a magnetically hard material having relatively high coercivity. The particles have dimensions transverse to their axes of elongation smaller than the magnetic domain size of the magnetically soft material.
