Voltage generation by ferromagnetic resonance
arXiv:cond-mat/0608022 · doi:10.1103/PhysRevLett.97.216602
Abstract
A ferromagnet can resonantly absorbs rf radiation to sustain a steady precession of the magnetization around an internal or applied magnetic field. We show that under these ferromagnetic resonance (FMR) conditions, a dc voltage is generated at a normal-metal electric contact to a ferromagnet with spin-flip scattering. This mechanism allows an easy electric detection of magnetization dyamics.
