  We inject a sequence of 1 ms current pulses into uniformly magnetized
patterns of the itinerant ferromagnet SrRuO3 until a magnetization reversal is
detected. We detect the effective temperature during the pulse and find that
the cumulative pulse time required to induce magnetization reversal depends
exponentially on 1/T. In addition, we find that the cumulative pulse time also
depends exponentially on the current amplitude. These observations indicate
current-induced magnetization reversal assisted by thermal fluctuations.
