摘要：

In magnetic tunnel junctions (MTJ) we study how the magnetic state depends on the tunnel current. We present data on the I-V dependence of the MTJ in strong biasing fields up to 4 V, and propose that the observed hysteresis may have its origin in spin-polarized electrons influencing locally the magnetic state of the system.
