SPIN-ORBIT COUPLING OSCILLATOR AND OSCILLATOR DEVICE INCLUDING SAME

摘要

An oscillator includes a nonmagnetic layer, a first magnetic layer and a second magnetic layer. The nonmagnetic layer provides a spin current of a spin direction polarized in a positive direction and a spin current of a spin direction polarized in a negative direction, wherein, the spin direction corresponds to the spin current generated based on the input current. The first magnetic layer is disposed on the upper surface of the nonmagnetic layer. The first magnetic layer varies first magnetism by the spin current of the spin direction polarized in the positive direction to provide a first oscillation signal. The second magnetic layer is disposed on the lower surface of the nonmagnetic layer. The second magnetic layer fluctuates due to the spin current whose direction of spin is polarized in the negative direction. An oscillator according to the embodiments of the present invention can increase an output by providing the oscillation signal based on the spin current of the spin direction polarized in the positive direction and the spin current of the spin direction polarized in the negative direction, generated based on the input current and a magnetic field generated by the input current.;COPYRIGHT KIPO 2016
