摘要: Nonvolatile resistive memory devices are disclosed. In some embodiments, the memory devices comprise multilayer structures including electrodes, one or more resistive storage layers, and separation layers. The separation layers insulate the resistive storage layers to prevent charge leakage from the storage layers and allow for the use of thin resistive storage layers. In some embodiments, the nonvolatile resistive memory device includes a metallic multilayer comprising two metallic layers about an interlayer. A dopant at an interface of the interlayer and metallic layers can provide a switchable electric field within the multilayer.

摘要: Spinwave transmission systems that include switching devices to direct the transmission of the spinwaves used for data transfer and processing. In one particular embodiment, a system for spinwave transmission has a first magnetic stripe configured for transmission of a spinwave and a second magnetic stripe for transmission of the spinwave, with a gap therebetween. The system includes a coupler that has a first orientation and a second orientation, where in the first orientation, no magnetic connection is made between the magnetic stripes, and in the second orientation, a connection is made between the magnetic stripes. The connection allows transmission of the spinwave from the first magnetic stripe to the second magnetic stripe. The first and second orientation may be the physical position of the coupler, moved by thermal, piezoelectric, or electrostatic forces, or, the first and second orientation may be a magnetic state of the coupler.
