Thermally assisted current-induced magnetization reversal in SrRuO3

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.
