An effective detection structure for a dynamical spin injection in a ferromagnetic/nonmagnetic metal bilayer has been developed. We demonstrate a clear detection of a highly symmetric signal, indicating a significant suppression of spurious signals due to the galvanomagnetic effects from the ferromagnetic layer. The angular dependence of the signal amplitude assures that the observed signal is caused by the inverse spin Hall effect due to the dynamical spin injection. We also find the importance of the eddy current that induces spin-rectified signals from a ferromagnetic layer.
