    摘要: Magnetoelectronic devices are fabricated by joining the edge of one ferromagnetic thin film element with the top, or bottom, portion of a second ferromagnetic, or nonmagnetic, thin film element. The devices also employ a new operational geometry in which the transport of bias current is in the film plane of at least one of the thin film elements, but is substantially perpendicular to the film plane of at least one of the thin film elements. Additionally, any of the variety magnetoelectronic devices (e.g., current-in-plane spin valves, current-perpendicular-to-the-plane spin valves, magnetic tunnel junctions, and lateral spin valves can be fabricated using these features.

    摘要: An electron spin-based device includes ferromagnetic layers with different coercivities, such that one of such layers is responsive to a magnetic field and the other is fixed. A value of an impedance in the spin based device for a spin polarized current varies in accordance with a relationship between a first changeable magnetization state and a second non-changeable magnetization state associated with such ferromagnetic layers.

    摘要: A modified hybrid Hall effect device is provided which is the combination of a conventional Hall effect device and a second Hall effect device having a Hall plate coupled to a ferromagnetic layer. The hybrid Hall effect device can be used to determine the independent magnetic field vector components comprising a vector magnetic field, such as for determining the x and the z components of a magnetic field, or for measuring the total magnitude of a vector magnetic field of any orientation. The modified Hall Effect device can be adapted for use as a magnetic field sensor for the detection of macroscopic objects that have associated magnetic fields, or for microscopic objects that have been tagged by microscopic magnetic particles. In one specific form, a plurality of hybrid Hall devices are electrically connected together to form an array in which a plurality of rows of hybrid Hall devices are electrically coupled to each other along a current axis, and the array is used for the detection of microscopic objects.

    摘要: A new type of magneto-electronic element, such as a spin transistor or hybrid hall effect device, can be used to construct memory systems to replace conventional cache, primary, secondary and long term (archival) storage. The magneto-electronic element is non-volatile, and has switching speeds and integration densities that compare favorably with conventional semiconductor random access memories, such as DRAM. In another embodiment, an integrated memory system may be constructed that synthesizes one or more previously disparate levels of conventional memory (i.e., a combination of primary and secondary storage) so that memory organization is further simplified and performance and cost are improved.

    摘要: A hybrid memory device combines a ferromagnetic layer and a Hall Effect device. The ferromagnetic layer is magnetically coupled to a portion of a Hall plate, and when such plate is appropriately biased, a Hall Effect signal can be generated whose value is directly related to the magnetization state of the ferromagnetic layer. The magnetization state of the ferromagnetic layer can be set to correspond to different values of a data item to be stored in the hybrid memory device. The magnetization state is non-volatile, and a write circuit can be coupled to the ferromagnetic layer to reset or change the magnetization state to a different value. The memory device can also be fabricated to include an associated transistor (or other suitable switch) that functions as an isolation element to reduce cross-talk and as a selector for the output of the device when such is used in a memory array. This latter arrangement also permits a bias supply to be applied to each cell in the array, increasing the output signal level, and the signal to noise ratio. A high resistance element such as a resistor or diode can also be used as the isolation element depending on the particular application. In a preferred embodiment, the hybrid memory device and associated selector are combined and integrally fabricated using conventional semiconductor processing techniques to increase the integration density of memory arrays using such devices.
