Abstract
We characterize the spin transfer torque induced reversal for current-perpendicular-to-plane spin valves with in-plane magnetic anisotropy at low temperature when driven by both direct and rf currents. We find that for rf currents with frequencies in the range of the dc driven resonances, the rf current strongly influences the preswitching precessional modes leading to a clear dependence of the critical dc switching current on the external rf frequency excitation.
