| 20 | High-harmonic Generation in Spin and Charge Current Pumping at Ferromagnetic or Antiferromagnetic Resonance in The Presence of Spin-orbit Coupling Related Papers Related Patents Related Grants Related Venues Related Experts View Highlight: One of the cornerstone effects in spintronics is spin pumping by dynamical magnetization that is steadily precessing (around, e.g., the z-axis) with frequency ω 0, due to absorption of low-power microwaves of frequency ω 0 under the resonance conditions and in the absence of any applied bias voltage. The two-decades-old "standard model" of this effect, based on the scattering theory of quantum transport, predicts that component I Sz of spin current vector (I Sx,I Sy,I Sz)α ω 0 is time-independent while I Sx(t) and I Sy(t) oscillate harmonically in time with single frequency ω 0; whereas pumped charge current is zero I≡0 in the same adiabatic α ω 0 limit. |
