Patent ID: 8049996

Claim:
A method of performing spintronics, the method comprising: providing a nonmagnetic, electrically conducting layer positioned adjacent to a first ferromagnetic electrode and a second ferromagnetic electrode; providing a static magnetic field B 0 to magnetize the first and second ferromagnetic electrodes, each direction of magnetization being substantially parallel to the static magnetic field B 0 ; providing an RF/microwave signal to the nonmagnetic, electrically conducting layer, the RF/microwave signal having a magnetic field B 1 which is substantially perpendicular to the static magnetic field B 0 ; interacting the magnetic fields B 1 and B 0 with conducting electrons in the nonmagnetic layer to excite a precessing electron state having a spin resonance frequency, thus generating a spin polarized conducting current; and detecting a change in the spin polarized conducting current.
