Thermally induced dynamics in ultrathin magnetic tunnel junctions

Piotr Ogrodnik , G.E.W. Bauer , K. Xia

Abstract

We consider the magnetization dynamics induced by thermally induced spin transfer torques in thin Fe|MgO|Fe tunnel junctions. The magnetization dynamics is described by the Landau-Lifshitz-Gilbert equation, including the thermal torques as computed from first principles. We show that the angular skewness of the torques importantly modifies the dynamics, e.g., leading to different instability criteria. © 2013 American Physical Society.
