Abstract

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 τ required to induce magnetization reversal depends exponentially on 1/T. In addition, we find that τ also depends exponentially on the current amplitude. These observations indicate current-induced magnetization reversal assisted by thermal fluctuations.
