  • Voltage controlled nonlinear spin filter based on paramagnetic ion doped nanocrystal
    Patent number: 6642538
    Abstract: This invention pertains to a device and a method for injecting spin polarized monochromatic electrons with a particular magnetic moment at room temperature and in absence of an external magnetic field into a nonmagnetic electrode. The device comprises a ferromagnetic electrode, a nonmagnetic electrode spaced from the ferromagnetic electrode, a nanocrystal doped with a single active paramagnetic ion disposed in the space between the electrodes, and an electrical connection between the electrodes for applying voltage to move the electrons from the ferromagnetic electrode, through the doped nanocrstal and into the nonmagnetic electrode.
    Type: Grant
