Query: Spin-orbit torque-driven magnetization switching and thermal effects
  studied in Ta\CoFeB\MgO nanowires   We demonstrate magnetization switching in out-of-plane magnetized
Ta\CoFeB\MgO nanowires by current pulse injection along the nanowires, both
with and without a constant and uniform magnetic field collinear to the current
direction. We deduce that an effective torque arising from spin-orbit effects
in the multilayer drives the switching mechanism. While the generation of a
component of the magnetization along the current direction is crucial for the
switching to occur, we observe that even without a longitudinal field thermally
generated magnetization fluctuations can lead to switching. Analysis using a
generalized N\'eel-Brown model enables key parameters of the thermally induced
spin-orbit torques switching process to be estimated, such as the attempt
frequency and the effective energy barrier.
