title = "Realization of a Spin-Wave Switch Based on the Spin-Transfer-Torque Effect",
abstract = "We investigate the amplification of externally excited spin-waves via the spin-transfer-torque (STT) effect in combination with the spin-Hall effect (SHE) resulting from short current pulses. In the case of overcompensation of the spin-wave damping, a strong nonlinear shift of the spin-wave frequency spectrum occurs. In particular, this shift limits spin-wave amplification from the SHE-STT effect. However, it allows for the realization of a spin-wave switch. At the corresponding working point, efficient spin-wave excitation is possible only in the presence of the SHE-STT effect with a spin-wave intensity that is a factor of 20 larger than in the absence of the SHE-STT effect.",
