A ferromagnet can resonantly absorb rf radiation to sustain a steady precession of the magnetization around an internal or applied magnetic field. We show that, under these ferromagnetic resonance conditions, a dc voltage is generated at a normal-metal electric contact to a ferromagnet with spin-flip scattering. The spin dynamics in the nonmagnetic region is accounted for by a frequency-dependent renormalization of the interface conductances. This mechanism allows sensing of time-dependent magnetizations by established dc electronic techniques. © 2006 The American Physical Society.
